Lisa: I can't believe I'm jealous of a baby!

Bart: Hey, so am I! When you're a baby, you can just spend all day rolling around on the floor. (sighs) I miss those days.

Lisa: You're laughing at him for something you made him do.

Nelson: Well… you're gay!

Lisa: People who call other people gay are often covering up their own latent homosexuality.
