Quote from Fez in No Quarter
Donna: Jackie! Jackie! Jackie: [wakes up] Hmm? Donna: I heard something underneath my bed. Jackie: Fez? Fez: [o.s.] [imitates cat] Meow! Donna: Fez, the cat's outside. Fez: [o.s.] [imitates dog] Woof, woof? [Jackie and Donna drag Fez out from under the bed] Fez: Please, let me stay. I promise I won't make a sound. Well, I do make some sounds, but they're happy sounds!
