George Costanza’s Wedgy - On episode No. 22 "The Library" (10/16/91) of the sitcom SEINFELD/NBC 1990-98 George Costanza (Jason Alexander) relived a high school incident when his cruel gym teacher Mr. Heyman initiated a  wedgie on him in the locker room. [To perform an Atomic Wedgie (worse that the regular wedgie) the underwear is stretched up over the victim's head while they were still wearing them.] Twenty years later George got another wedgie from Mr. Heyman [now a homeless man] when he met him on the steps of the New York Public Library.

TRIVIA NOTE: The "Wedgie" was referred to as a "Melvin" on the NBC sitcom BOSTON COMMON.
