Daphne: Well, then do what I do when I want Eddie away from me. I make a sound like [high-pitched wail] [Eddie runs away and buries his head in a cushion] Martin: That's mean! Daphne: Why? It doesn't really hurt his ears. He just finds certain noises irritating. [Frasier and Niles return from the opera, singing. Eddie runs out of the living room]
