- James Isaac 'Jimmy' Neutron: AAAHHH! An "F"! It burns!
- [cries in pain]
- [Timmy is cornered by Mr. Crocker]
- Timmy Turner: Look! A child in pain!

- Cindy Vortex: Tell me more about your interests, Timmy Turner. What makes you tick?
- Timmy Turner: Stuff makes me tick. Junk makes me tick too. But wicked-awesome stuff, that's what really makes me tick.
- Cindy Vortex: [stunned] Incredible. The technology you're talking about must be on the cutting edge of the latest scientific paradigms.
- Timmy Turner: You talk funny.
- [Timmy mutates a squirrel for the first time]
- Timmy Turner: [laughing] You were right, Cindy. Mutating stuff is easy.

- Cindy Vortex: Really?
- Timmy Turner: Well, not a lot of girls talk to me, so... yeah!

- James Isaac 'Jimmy' Neutron: [after Timmy is sucked into the Hyper-Cube] Ha! Serves you right.
- [notices Timmy's Auto-Poofer in his hand]
- James Isaac 'Jimmy' Neutron: Oh, wait a minute. This isn't my mini laser.
- [taps it in his hand and accidentally poofs himself away]
- Timmy Turner: [pulls himself out of the Hyper-Cube] I meant to do that.
- [notices Jimmy isn't there]
- Timmy Turner: Hey, where'd he go? Must've scared him off. Which means I finally got the greatest lab in the universe all to myself!
