Plot summary
Elaine and Jerry, both sex-deprived, become friends with benefits. Not wanting relationship drama, they make rules to relieve themselves of obligations, but George warns that they cannot have their cake and eat it too. Elaine indeed twists a rule around on Jerry when he tries to go home after sex, putting him on guard as he shops for a birthday present for her. They discover that commitment-free sex is impossible when Jerry's unromantic gift and birthday wishes prove disappointing, while Kramer upstages Jerry with gifts from the heart. Jerry must choose whether to get back together for the sake of saving their friendship.
