"Doing His Homework" joke
Grandma, who was living with her daughter's family, greeted her 11-year old grandson at the door when he came home from school.
"Well, sonny, what did you learn today?" Grandma asked.
"Sex education," he replied. "All about sex organs, intercourse and stuff."
The old woman was so shocked, she immediately reported the conversation to her daughter.
"Calm down, Mom," her daughter replied. "These days it's all part of the cirriculum."
A few hours later, the grandmother was reading when her daughter called out that dinner was ready. Grandma walked past her grandson's room and noticed that he was vigorously masterbating.
"Sonny," Grandma said, "when you're finished with your homework, come downstairs to dinner."
