Quote from Lilith in Take Me Out of the Ball Game
Lilith: Oh. One other thing. Frasier: Mmm, yes. Anything, my angel. Lilith: Would you stop by the lab and pick up a short-haired rat-- l.D. number 17-A? Frasier: Oh, Whiskers. Lilith: Yes. I call him that because his whiskers are so pronounced. Get it? Whiskers... Whiskers. Frasier: Humor is all about making those connections, darling.
