Quote from Kramer in The Library
Marion: Yes? Jerry: Yes, I called before. I got his notice in the mail. Marion: Oh, Tropic of Cancer, Henry Miller. Uh, this case has been turned over to our library investigation officer, Mr. Bookman. Kramer: Bookman? The library investigator's name is actually, Bookman? Marion: It's true. Kramer: That's amazing. That's like an ice cream man named, Cone. Marion: Lt. Bookman has been working here for 25 years so I think he's heard all the jokes.
