  • Episode Description
  • When Fry eats an egg-salad sandwich from a vending machine at a gas station, he begins to have strange side-effects -- he becomes stronger and smarter. Professor Farnsworth makes a diagnosis and concludes that Fry had ingested "intelligent worms" that have set up shop in his body. Because these worms are so smart, the regular means of flushing them out will not work. The Planet Express crew makes miniature robotic versions of themselves and enter Fry's body to fight off the intruders. Meanwhile Leela is left to divert Fry's attention, but finds herself more and more attracted to the new man Fry has become. Leela ends up loving Fry, or at least what he has become. In the end Fry makes the worms leave, and Leela leaves him, because he turns back into the old Fry.moreless

  • Quotes (60)

    • Sal: Yo sexy mama, let's get busy and freaky, in that order. Fry: Hey jumbo, how would you like it if Leela said you were sexy and she wanted to make love with you? Sal: Eh.. I've gots five minutes. She looks pretty good for a truckstop chick. Fry: You take that back! She does not look good for truckstop chick. Sal: Yeah, you're right. She don'ts got enough meat for a guy like me. Fry: She does too. She's loaded with meat. She's got more meat than a cow!

    • Bender: Sorry you struck out, sausage link. If it's any consolation, my life is great! Babes! Bucks! I got it all! Fry: Well, at least I learned Leela's a lost cause. I give up. Bender: There you go! Goodnight. I gotta get up early to go parasailing with movie stars!

    • Fry: I got rid of the worms. Leela: What? Why would you do that? Fry: Leela, I had worms. I needed to know who you loved. Me or them. Leela: Well... which of you wrote me that sonnet? Fry: I did... I think. It was probably about 50/50. But that's how I really felt about you, I swear! Leela: I don't know. Fry: Please. Give me a chance to be romantic on my own. I've got a baggy of massage oil, and I'm gonna give you my super back rub, just like I used to give Amy when I was going out with her, and she always seemed- (Leela stares angrily at him) Uh-oh!

    • Leela: Fry? I missed you. Did you find out what you needed to find out? Fry: I'm about to. Leela, let me play for you one for time. Leela: You don't have to do that. I'm still seduced from before.

    • Fry: I was just working my way towards the medulla oblongata, control centre of the heart and lungs. And if I kill myself, you die with me. Worm Guard: Wait a minute, man! Fry: I hope Satan has a nice colon, 'cause that's where you're gonna be living!

    Notes (5)

    • Alien code: In the season 3 DVD, there is a section where you can learn how to draw Fry. The background is from the truck-stop bathroom. On the wall we see Alien Code #1. When translated it says "For a moderately good time call 555-1972!"

    • Alien code: When Fry walks into the truck-stop bathroom, there is a ton of Alien Code #1 written on the wall. While most of it is just single letters, there is one phrase you can read on the calendar. It says: "For A Good Time Call..."

    • Alien code: In the opening sequence of convoy trucks going by, one of the trucks has Alien Code #1 written on it. When translated it says: "Human Milk."

    • Alien code: Alien Code #1 makes another appearance when Fry and Leela are walking down the block and run into Sal from the truck-stop. It says: "Watch For Falling Humans."

    • For this episode, storyboard artist Rodney Clouden won an Emmy award for Outstanding Individual Achievement in Animation.

    Trivia (21)

    • As the miniaturized Planet Express ship is traveling down Fry's ear canal, a long shot shows Fry twisting his finger back and forth. Inside the ear canal and at the same time, Fry's finger is being inserted with no rotational motion.

    • At the truck stop Leela scrapes a Voyager satellite off of the windshield of the ship. Voyager 1&2, launched in 1977, are currently the furthest manmade objects from Earth.

    • In the scene where Leela blows mini Leela into Fry's ear her aim is perfect especially if you take into consideration the distance she was at.


    • The scene inside Fry's body where Zoidberg says "I've heard of that. Who says I haven't?" The gun Zoidberg is holding switches hands between cuts, then switches back again.
