Quote from Ross in The One with the Truth About London
Rachel: Okay, maybe they are not funny to you- Carol: [o.s.] Oh, my God! Rachel: Or Carol. But they're funny to kids. And who is it hurting? Ross: Uh, you know what? I’ll tell you who it hurts. It hurts the kid who has all his clothes stolen in gym class so he has to go to the principal's office wearing nothing but a catcher's mitt! Rachel: That was you?! We heard about you in Junior High! Did you really just shake your fist in the air and shout, "I will be avenged!"
