Zack comes home from school one day and is met at the door by his bubby, who asks what he learned in school today. He replied, “We learned about sex.” His grandmother just stands there, almost in shock. Then later that day she tells his mother about their conversation, and the kid's mom says, “Mother, sex IS a regularly studied subject in school these days.”

Later that evening, bubby walks past Zack's room, sees him vigorously masturbating, and says to him, “After you finish your homework, come down for dinner.”
