Beakman's World Season 4 Episode 5

Beakman: And then there's the face-peeling, knee-buckling barf breath that can clear an elevator between floors! (about bad breath)

Lester: Wait a minute, are you saying you went to a human mouth on your vacation?
Beakman: You know, Lester, some of the very best vacations are right under your nose.

Lester: I have not yet begun to disgust!

Lester: (with a shell to his ear) You know what's weird, I hear Billy Ocean.

Phoebe: Let's give a big Those Disgusting Animals welcome to worms!
Lester: Taxi!

Phoebe: Many worms are hermaphrodities which means they have both male and female organs.
Lester: That's a little bit more than I need to know!

Phoebe: Say hello to the ever popular manure worm!
Lester: You mean, these guys actually live in manure?
Worm: Well, we don't live in Cincinnati!

Lester: You know, there's nothing so satisfying than a good vintage manure. I always forget which manure goes well with fish.
Worm: White zinfam-bug.

Lester: Compost... that's something I could really get into.

Beakman: I'm incontinent with curiosity. Phoebe, diaper me with a question!

Phoebe: Hey, where's Dr. Lemuel Gulliver?
Lester: I don't know. Maybe Beakman hasn't been keeping up payments on his smoky door of history.

Tiny Voice: Help me! Help me!
Phoebe: Do you hear that?
Lester: Yeah, where's it coming from?
Tiny Voice: Help me! Help me!
Phoebe: Lester, it's your feet!
Lester: I knew they could smell, but I never heard them talk!

Lester: You mean, a cube is supposed to be the same height, width and length?
Phoebe: Much like you.
Lester: Oh... hey!

Phoebe: So, Shaylyn Officer of Enid, Oklahoma, I wouldn't lose any strength about giant insects.
Beakman: They may make good movies, but they make bad science.

Phoebe: We're out of time!
Beakman: And out of breathable air!
(because of Lester's breath through the episode)
