George Costanza's burn that he invented in response to a co-worker telling him that "Hey George the Ocean called, they are running out of shrimp" He thinks it is the greatest diss ever, but all his friends don't laugh at it
From the show Seinfeld
George: The Jerk Store called, They're running out of you!
Jerry, Kramer, and Elaine: Ehhhh
background:
I first heard "jerkstore" on an episode of Seinfeld. George (Jason Alexander) was at a business meeting, eating a whole mess o' shrimp. This other guy says, "Hey George, the ocean called, they're running out of shrimp." Everyone has a good laugh and George is speechless. On the drive home, he thinks up a comeback "Oh yeah? Well, the jerkstore called, they're running out of you."
