Quote from Mitchell in Little Bo Bleep
Cameron: Lily, that is a bad word, and you are not allowed to say it ever. Lily: But it makes you laugh. Mitchell: Okay, well, daddy shouldn't be laughing, and you should never say that word. Do you understand? Lily: Maybe. Mitchell: Okay. This is not a game, all right? If you say that word one more time, I'm gonna take away all your toys! I'm serious! She knows I'm not serious.
