Seinfeld, Season 8

George:
Listen to the comeback: "Oh yeah? Well the jerk store called. They're running outta you."

[Jerry, Elaine, and Kramer stare blankly at him]

George:
Wha...You gotta be kidding me?!

Elaine:
How 'bout this one? How 'bout, "Your cranium called. It's got some space to rent."?

George:
What does that mean?

Jerry:
Hey, here you go: "Hey, Reilly. The zoo called. You're due back by six."

George:
No. No, no, no. You're not helping me.

Kramer:
Look, just tell him you had sex with his wife. That'll kill him.
