Hymie is sitting in the dentist's chair and is just about to have some extensive and expensive cosmetic work carried out on his teeth. Moshe his dentist smiles at him and says, "Just before I start, Hymie, I'd like to tell you how lucky you are coming to me for this work. When I've finished with you, you'll be another man entirely."
"I'm pleased to hear that, Moshe," says Hymie. "So don't forget to send your invoice to this other man."
