E.T.

D. and I, laying quietly together in bed, listening to the boys' conversation in the next room:

Moono: Don't punch my nuts.
Peanut: I didn't punch your balls.
Moono: They're not balls, they're nuts.
Peanut: Ha. I punched your balls.
D, hollering: No punching in the testicles, boys!
Moono: Nuts.
Peanut: Balls.
Me, hollering: Testicles! They're called testicles!
Peanut, laughing: Testicles.
Moon, laughing: Testicles.
Peanut, laughing: Testicles.
Moon, laughing: E.T., the Extra Testicle.
Peanut, laughing harder: E.T., the Extra Testicle.
Moon, now hysterical: E.T., the Extra Testicle.
Peanut, also hysterical: E.T., the Extra Ball.
