Little Johnny's First Day of School

Little Johnny left for his first day of school early in the morning. At the end of the school day the bus drops off all of Johnny's neighborhood friends, but he is not with them. After an hour of waiting, Little Johnny's parents start getting worried and are about to call the cops when their son walks in the door. Worried sick, his parents ask where he's been. "I've been at school having sex with the teacher!" Furious, little Johnny's mom grounds him and sends him to his room while his dad goes along with his mother's decision. After about an hour, little Johnny's dad goes up to see how his son is doing. He says, "Son, I'm proud of you. It took me two whole weeks to score with the teacher and here you are getting lucky your very first day of school! If there is anything you need help with, let me know." Little Johnny looks up to his dad and says, "Dad, how do you make your butt not hurt?"
