Reese: What did you hear?
Dewey: Everything. I want to go to the fair.
Malcolm: No, Dewey. You're too young.
Dewey: Take me or I'll tell Mom.
Reese: If you do, I'll just stomp the crap out of you.
Dewey: Go ahead. I'm still telling.
Malcolm: Dewey, you're not going and you're not telling. If you blab to Mom, we'll take every pet you ever get and set it free.
Reese: We'll destroy every toy, every game, everything you ever love.
Dewey: Do what you have to.
