This play isn't exactly piping hot. Hamm actually curses his father for giving birth to him at all. He looks down on Nagg for giving into his animal drives and procreating. As for sex, there's none. The only near-sexual act is when Nagg and Nell try to kiss each other from their separate trash bins. They fail. We only rated Endgame PG because of the negative attitude that it presents toward sex and procreation at all.
