Quote from Elaine in The Heart Attack
Elaine: Whose tonsils grow back? [laughs] Doctor: It happens. Jerry: Yeah, if you've been exposed to gamma rays. Elaine: I still have my tonsils. Everyone in my family has their tonsils. In fact, we were forbidden to socialize with anyone who didn't have their tonsils. Doctor: That's interesting. Because, no one in my family has their tonsils, and we were forbidden to socialize with tonsil people. Jerry: Well, it's like the Capulets and the Montagues.
