Quote from Roz in Goodnight, Seattle
Roz: You have got to let these people in. Frasier: Yes, Roz, I'm sorry. I know it's warm... Roz: No, it's not the heat. That truck that just crashed was full of cattle. Frasier: Well, the sound of gentle mooing in the background might lend a pastoral effect. Roz: Cattle, Frasier. Large, un-diapered cattle that just heard a cannon go off.
