- Let's watch an episode of
"Futurama," "Parasites Lost." I'm excited to get wormy with it. (zipper unzipping) - [Fry] Okay. Yeah. Mm! - Oh! Egg salad from a
gas station bathroom? Oh. You can't imagine the amount of bacteria that can grow on old egg salad. When we test our medical
boards, there's certain foods that are labeled as
potentially problematic, especially when you reheat them. Reheated rice, reheated
potato salad, egg sandwiches, raw chicken, raw meats, obviously. Seeing an egg sandwich causes
some kind of serious flashback from me to my med school days. All that's coming to mind
from my medical board is salmonella, salmonella, salmonella, which causes massive
inflammation in your intestines, which causes a massive fever. You can get really sick from it. Like, you can go into sepsis
from that kind of infection. - You're not going to eat a sandwich from a truck stop men's room are you? - Eh, what's the worst
thing that could happen? - A lot of things can happen. Not only can that salmonella be there, but remember every time a public toilet or any toilet for that
matter gets flushed, the bacteria that's inside that toilet gets shot out across the bathroom. And if there are those hand air dryers that everyone thinks are all so fancy, they just blow around that bacteria. So know that there is e. coli everywhere. I kind of miss the days of when we were able to close the toilets before flushing them in public bathrooms. (Fry chewing) - Ugh. It's like a party in my mouth
and everyone's throwing up. - (laughs) Oh, that's so gross. That's an illness that's
gonna have very rapid onset. So if someone eats something suspicious and then gets sick three, four days later, I wouldn't necessarily think
it's because of the food. Suspicious food intake
usually causes illness within the next 24 hours. (pipe squeaking) - There. Fixed forever. (gasket blowing) (Fry and Bender gasping) (tank exploding) - [Scruffy] Oh, marmalade. (bright music) - Dr. Zoidberg? A medical corporation? You know these days we don't
have individual doctors running corporations. In fact, every doctor is seemingly joining huge medical networks, which, recently there was a law passed by the FTC that may change things around. Because when doctors used to
work for a medical organization and then they would get unhappy, they would struggle to
find the courage to leave, because they would sign something known as a non-compete clause. But now the FTC is saying
all non-competes are illegal, and all of them don't apply, so now doctors can technically leave and take their patients with them, Where before that wasn't a possibility. - Oh!
- Oh, the hypochondriac's back. - That's not a hypochondriac, my guy has a pole going through him and it's not a "Grey's Anatomy" episode. - So what is it this time? Well, my lead pipe hurts a little. - That's normal. Next patient. - Sounds like my dad whenever
I was complaining to him. For those who don't know,
my dad is a physician, and anytime I would complain
to him about anything hurting, "Dad, my neck hurts." "You're fine." "Dad. I don't feel good. I have a fever." "Go to school. You're fine." Now that I'm thinking about it, like, if I had a fever, I was contagious. You probably shouldn't
send me to school, man. (pipe sawing and clattering) - [Bender] Hmm. (body suturing) - Whoa. Kind of reminds me of
that Phineas Gage story where the guy got the giant
thing, the railroad track, like blown right through his head, and it was able to survive
for a pretty lengthy period of time with some
personality changes. There were some questionable
tidbits to that story, and I covered that in a
whole other YouTube video, but very, very interesting stuff
how one person can survive. - Fry, did you eat
anything unusual recently? - No. - What about that bathroom
egg salad from the truck stop? - I've had better. - Egg salad? Hmm. Zoidberg will have to examine
your gastrointestinal tract. - Here's what I would do to
examine someone's GI tract. Before palpating the area,
I would observe the area, meaning I would look
for rashes on the area. Then I would take my stethoscope and listen to the four quadrants, and see if there were bowel sounds present and if they're increased,
decreased or normal. Then I would lightly palpate the area. Then I would deeply palpate the area. Then I would do some special tests where we could actually decide if someone's having a gallbladder issue, if they're having appendicitis. And from that physical exam, we can then point to
certain GI conditions. Matching up with of course
the subjective history that was told to us. - We'll need to have a look
inside you with this camera. Guess again.
(Dr. Mike laughs) - So upper endoscopy can
check out the esophagus, the stomach, the small intestine. But once you wanna go into the
colon, the large intestine, the rectal region, you're
gonna have to use probably a full-on colonoscopy from down below. What's pretty cool is when
they do a colonoscopy, they actually blow air in to make sure that they can see the area completely, because you want to be able to catch cancers, polyps, et cetera. And what's interesting
is the amount of time that a doctor spends
pulling the scope out, meaning slowly rechecking the area, pretty closely correlates
with their ability to not miss lesions. (tense music) - Watch for any subtle
irregularity in Fry's bowel. (awe-inspiring music) (Dr. Mike laughing) - Star Wars mansion! (lasers blasting) One of the more common things
that we find on colonoscopies is something known as diverticulosis, where you have like a little outpouching inside the large intestine. That usually happens as a result
of over time bearing down, especially if someone has
constipation quite often. And on its own it's
usually not problematic, but if it gets infected, that diverticulosis can
become diverticulitis, and that does require in many cases, inpatient management in IV antibiotics. (Crew gasping and groaning) - [Amy] Worms? - So the eggs in that
egg salad sandwich were- - Correct! Worm eggs. And the mayonnaise was
probably none too fresh either. - It's nauseating, mon! (munches popcorn) is there no way to get rid
of the disgusting maggots? - There are all sorts of
worms that humans get. We call them parasites, 'cause
they're parasitic in nature, meaning that they eat
off of our food supply. You know, they happen, especially if you have poor sanitation, if you are consuming poorly cooked meats. But we do have medications
that treat them. - We'll have to travel
deep inside fry in this! (dramatic music) (dramatic music) - Oh! This is like a capsule endoscopy. One of the ways that we can
look inside someone's GI tract is to swallow a pill camera. It basically generates these images for the internal part of the
bowels and you're able to see if there's any issues. I've seen it used for
instances of bleeding. Is there something that we
need to go in and treat? Especially if a patient is
a little bit more fragile. (machine buzzing) (machine beeping) - Wow. So this is what they mean when they say, "I wish I was a fly on the wall." - Your net suits will let you experience Fry's worm infested bowels as if you are actually
wriggling through them. - Why not just give him like, albendazole, or one of these anti-parasitic medications and be done with it? - [Farnsworth] Is everyone present? - Aye-aye!
- Yes. - [Hermes] Definitely. - Here's the plan. We'll enter the ear, drip
down the back of the throat. - Enter the ear? Why not
just go into the mouth? Why the weird entrance? - And make for the bowel. There, we'll irritate the
pelvic splanchnic ganglion and cause an intestinal spasm, expelling, among other
things, the parasites. - You know when the GI tract is irritated, it spasms on its own,
and it gets irritated, and it creates diarrhea, and
diarrhea washes the area out. That's why diarrhea is
like, a survival thing. But it can also harm you, obviously, if you're not able to rehydrate. - Fry can't know anything
about the mission. If he finds out, the worms
will try to defend themselves. Leela, your role is to distract
fry so he doesn't notice- - Aren't they microscopic?
How does she see them? Or maybe her one eye is
just like, really good. - Look, a starling! - Really? (ship sailing) - Oh, wow. Good accuracy. Alright, so that's ear wax. Ear wax is protective. Everyone
wants to get rid of it. I don't know why. There has to be some kind of
negative PR about ear wax, but unless it's fully clogging your ear, it's there to do its job, which is protecting the ear
canal, keeping insects out. Actually, ear wax prevents water from damaging the ear canal. So by removing it and keeping it clean, you're actually making it more susceptible to getting infected. - What if we go for a walk possibly, because it's such a lovely day, perhaps? - I'd love to. (ear squishing) (Dr. Mike groaning) (Crew gasping) - We've gotta get someplace
where he won't stick his finger! - It's hopeless! Abandon ship! - Wait, we just have to
get past the eardrum. - How are they gonna get past it? Oh, they just went straight through it. - [Hermes] What are those
worms doing to Fry's brain? - [Farnsworth] They're
giving it a complete tuneup. - There are actually some worms that can actually make
their way to the brain. One that comes to mind is
like, the pork tapeworm. It can cause cysts in the brain. So this episode has some truth to it. - Brace yourselves everyone. We're entering the interior of Fry's nose. - We're at finger alert five. (alarm blaring) - Let's just pray nothing stimulates the delicate smell receptors. Nobody make a smell. - Not the smell receptors. The cilia, you bother the cilia. Oof. They get that itch in
there, makes you sneeze. (Fry sniffs) (crew screaming) Little pollen action. - Quick! We can escape through that
nasal capillary into the sinus. - Strange. Usually you don't know
anything about human anatomy. - I learned it from a
decongestion commercial. - The decongestants, the way they work is they constrict the capillaries, the small blood vessels inside the nose. And when that happens you
have less mucus production, so people feel like they're clear. But usually if you use
it for a period of time, you get used to it, you need more of it. And then if you stop using it abruptly, you get this rebound congestion with a ton of mucus just coming out. That's why I'm not a fan
of those nasal sprays, the nasal clearing nasal sprays. I love the nasal salines. - Ah, the stomach. Scenic
gateway to the bowel. - Why is there a penny in the stomach? (alarm blaring) Oh, the worms, they're
sending their defense. - Abandon ship! - This reminds me of like
an h. pylori infection, which is a bacteria. And what's interesting is they
actually protect themselves from the gastric juices of the stomach. So they have their own
protective mechanism. I don't know if the worms
have this in the GI tract. - Don't give up now. We're but a stone's throw
from the pyloric sphincter. - Okay, so that's the
sphincter of the stomach. Okay. - There it is. The stately
capital of Fry's bowel. A heavily guarded fortress surrounding the pelvic
splanchnic ganglion. - I've heard of that. Who said I haven't? - If we can stimulate that
nerve, the bowel will convulse, expelling the entire worm society. - The bowel's made up of smooth muscle, and it has a motion that
is pretty consistent called peristalsis, where by
this like, unique movement, it pushes food through it. So the fact that they're saying convulse, I don't know exactly
what they mean, cramp? - Let's smush some worms. (lasers firing)
(dramatic music) - Worms to bottle stations! (lasers firing) - Next time I give a
patient an anti-parasitic, like some albendazole thing,
I'm gonna literally imagine that this is what's happening. Or just show this scene to the patient. They're gonna be like,
"What are you showing?" (lasers firing) - The nerve is through
here. Where's Zoidberg? - Yippie Ki-yay! You'll
never guess where I've been! - Is that a sperm? - I love you! - You do?
- Yes! But it's only recently that I've been able to articulate my thoughts. I love you Leela. And I always have. - Fry, that's the
sweetest, most wonderful- Wait. Recently? Like since you
ate that toilet sandwich? - Yeah. I don't know why, but my life
really turned around that day. - Why are the worms helping him? You know, if you eat a
tape worm can grow so long, like many feet in length, and it could eat so much of your nutrients to take away your nutrients,
where you can become anemic, you can actually start losing
mega amounts of weight, 'cause the tapeworm is just feeding on what's supposed to be your sustenance. - Stay here. (Fry sighs) - Freshen your Nocatina? - Please. I need something
to settle my stomach. (explosions booming) (lasers firing) - I feel like if you suffer with IBS, this is what's going on in your
stomach, just all the time. Oh! Oh! (crew yelling) - [Amy] Oh! I'm okay. - Leela, you ignorant dope!
- Did you ever stop to think that Fry is better off with worms? - I feel like this deserves
to be its own TikTok thing. They have the parasite cleanses where people are doing
these ridiculous things to cleanse from parasites,
which is just strange. Now they're having parasite love videos, where people end up
loving their parasites. - Oh, Fry. I love what you've become. - What I've become. - What is it? - There's just something
I have to find out. - What is he, is he gonna poop? - Who controls this bowel? - Who wants to know? (worms gasp) I am the Lord Mayor of Cologne! - Cologne! - You mean Colon? - State your business. - Your excellency. Have
you ever been in love? - No. - Doesn't he know you should never
negotiate with terrorists? They're terrorizing his cologne. - A wonderful girl loves me, but I need to know if
it's really me she loves, or just what you worms have made of me. That's why, with all due
respect, I'm asking you to leave. - I wish I was more well-versed on worms to know what kind of worm this resembles. I'm gonna guess roundworm. So I'm gonna pop up a picture
here and if I'm wrong, I apologize, but that's
what my limited worm appearance-educated mind thinks. - No one can make me leave! (dramatic music) (swords clashing) (elevator dinging) - What kind of elevator
exists in the colon that gets you to the brain? (dramatic music) (neurons zapping)
(swords clashing) (dramatic music) - Everyone outta my body
or the brain gets it! - He's bluffing. - What, he's gonna (censored) himself? (neurons zapping) Oh, he's cutting neurons. (dramatic music) The axons! The myelin sheaths! (Fry grunting) (dramatic music) - You've damaged your brain, universe, but no more than a week of binge drinking or five minutes on a cell phone. - I was just working my way
toward the medulla oblongata. - Not the medulla oblongata! Oblongata? That reminds me of
that scene from "Water Boy." - Oblongata! (signal beeping) - I hope Satan has a nice colon, 'cause that's where
you're gonna be living. - What would they care, if he's asking 'em to leave,
they're gonna die anyway. Well, at least pinworms can survive like, two to three weeks
in the outside environment. That's actually why they spread so quickly in childcare centers, 'cause a child scratches their butt, and they just laid those eggs there, then eggs get underneath the fingernails, then the child gets on their clothes and they spread it to another child. - Stop! We'll leave. But one day you'll be eating
a fast food burger and boom! You'll be crawling with us again. Ever wonder what makes
special sauce so special? - Yo. - Yo. I would usually say me, even if you're trying to
do it in Spanish, yo is I. There's actually some
phenomenal stories of animals, animals, being found inside humans. Click here to check that out, and as always, stay happy and healthy. (upbeat trap music)
