Kramer, George, Jerry, and Elaine sit by and watch while a man is carjacked. They are arrested for not acting under the town's new Good Samaritan law. The law is designed to overcome individuals' incentive not to come to others' rescue; we can think of this as a law that changes payoffs in a game matrix.
Jerry does something nicer for his dry cleaner, who then extends his family a discount. Jerry's girlfriend claims to be his wife in order to get the discount.
George asks Lupe, the maid at his hotel, to untuck the sheets at the foot of his bed, because he can't sleep if the sheets are too tight, George is disappointed in Lupe, who didn't untuck his sheets as she had promised. Jerry asks George if he remembered to tip Lupe, but George forgot (no incentive after you're gone and if you're not coming back). Jerry says, "That's why communism failed."
