[Fry walks out of a bathroom carrying a "Fresh" Egg Salad Sandwich he just bought from a dispenser]
Bender: What's that black cracker?
Fry: A tomato.
Leela: You're not going to eat a sandwich from a truck stop men's room, are you?
Fry: Eh, what's the worst thing that could happen?
[Takes a bite]
Fry: Ehh, it's like a party in my mouth, and everyone's throwing up.
[Smart Fry visits Leela's apartment]
Fry: Apartment 1-I. The old me would have made fun of that.
Fry: Everyone out of my body or the brain gets it!
The Lord Mayor of Cologne: He's bluffing. No creature would voluntarily make an idiot of itself.
Fry: Obviously, you've never been in love.
Hermes Conrad: [Cruising around Fry's muscles] Soon he'll be stronger and more flexible than Hercules and Gumby combined!
Dr. Zoidberg: Gumbercules? I love that guy!
[after shrinking down to microscopic size in order to enter Fry's body, Zoidberg comes in riding a sperm]
Dr. Zoidberg: Yippy ki yay. Guess where I've been.
The Lord Mayor of Cologne: Stop! We'll leave, but someday 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.
Dr. Zoidberg: We'll need to have a look inside you with this camera.
[Fry opens his mouth]
Dr. Zoidberg: Guess again.
Bender: Where are we? The ass?
Professor Hubert Farnsworth: We're in the heart, better known as the love muscle.
Dr. Zoidberg: Where the food is digested.
Professor Hubert Farnsworth: [whispers] Shh, be very quiet. We're in the ear.
Amy Wong: [whispers] Okay, Professor.
Professor Hubert Farnsworth: WHAT?
Bender: Who are you?
Scruffy: Scruffy. I'm the janitor.
Bender: Then why aren't you fixing the boiler?
Scruffy: Schedule conflict.
[slowly flips page on porn magazine]
Hermes Conrad: We gotta get someplace where he can't put his finger.
Bender: It's hopeless! Abandon ship!
[Fry has been impaled by a lead pipe and is seeing Zoidberg for help]
Dr. Zoidberg: Ah, here's the hypochondriac. What seems to be the trouble now?
Fry: My lead pipe hurts.
Dr. Zoidberg: Perfectly normal. Next!
[Fry threatens the parasites in his colon]
Fry: I hope Satan has a nice colon, 'cause that's where you're gonna be living.
[Zoidberg scrapes cholesterol off Fry's artery]
Dr. Zoidberg: It's good cholesterol, but it spreads like bad cholesterol.
Leela: I haven't felt this happy since Double Soup Tuesday at the orphanarium.
Fry: When I'm with you, every day feels like Double Soup Tuesday.
Professor Hubert Farnsworth: If we can stimulate that nerve, the bowel will convulse, expelling the entire worm society.
Hermes Conrad: But what about the worms in the other parts of his body?
Professor Hubert Farnsworth: Listen, this is going to be one hell of a bowel movement. Afterwards he'll be lucky if he has any bones left.
Fry: It's like there's a party in my mouth and everybody's throwing up.
[the gang are operating microscopic VR robots of themselves. Their mission is to enter Fry bowels and rid him of parasitic worms]
Professor Hubert Farnsworth: In each Gastro Survival Kit you'll find a rain slicker, a disposable Fun Camera and something to protect you against bacteria, a harpoon!
Bender: Yo, old guy. Why do we need to use those tiny microdroids? Can't you just shrink us?
Professor Hubert Farnsworth: Oh, my, no. That would require extremely tiny atoms, and have you priced those lately? I'm not made of money. Leave me alone!
Professor Hubert Farnsworth: Brace yourselves, everyone. We're entering the interior of Fry's nose.
Bender: We're at finger alert five, people.
Fry: Of all the parasites I've had over the years, these worms are among the... hell, they are the best.
