'Spare a Square'
"The Stall": Season 5, Episode 12
It's elevated bathroom humor, Seinfeld-style. Upon discovering there's no toilet paper in her stall, Elaine asked her restroom neighbor if she can hand her some TP from her stall. Elaine is informed by the stallmate next door (Jerry's girlfriend, she'd find out later) that she "can't spare a square" of toilet paper. It was perhaps the most selfish moment in TV history, but this situation has undoubtedly played itself out a million times in real life. This episode also introduced us to the term "mimbo," short for male bimbo.
