Quote from Phoebe in The One Where Chandler Doesn't Like Dogs
Monica: Phoebe. Phoebe, open up. [dog barks] Phoebe: There's no dog in here. Chandler: Phoebe, we can hear the dog barking. Phoebe: No, that's just me coughing. [Phoebe coughs, dog barks] Oh, good. There you are. Listen, I have a dog in my room.
