Tim Whatley is Jerry Seinfeld's dentist. He converted to Judaism, and Jerry thinks it is just to be able to make jokes.

Tim: "You have no idea what my people have been through."
Jerry: "The Jews?"
Tim: "No, the dentists. Did you know we have the highest suicide rate of any profession?"
Jerry: "Is that why it's so hard to get an appointment?"
