Quote from Kramer in The Fusilli Jerry
Jerry: Who would order a license plate that says "Assman"? George: Maybe they're Wilt Chamberlain's. Jerry: It doesn't have to be someone who gets a lot of women. It could be just some guy with a big ass. Kramer: Yeah, or it could be a proctologist. Jerry: Yeah. Proctologist. George: Come on! No doctor would put that on his car. Kramer: Have you ever met a proctologist? Well, they usually have a very good sense of humor. You meet a proctologist at a party, don't walk away. Plant yourself there, because you will hear the funniest stories you've ever heard. See, no one wants to admit to them that they stuck something up there. Never! It's always an accident. Every proctologist story ends in the same way: "It was a million-to-one shot, Doc. Million-to-one."
