Antonio came home from school one day and walked into the kitchen. His grandma asked him, "Antonio, what'd you learn in school today?"
Antonio replied, "Well, we learned about penises, and vaginas, and sexual intercourse, and masturbation."
Grandma hauled off and slapped Antonio, hard. He ran up to his room, crying.
Antonio's mother walked in and cried, "Ma! Why did you go and hit Antonio!?"
Grandma replied, "Well, I asked him what he learned in school today. He started talking about sex, and penises, and masturbation!"
Antonio's mother said, "Ma! That's what they do learn. It's called sex education!"
Well, Grandma felt so bad about hitting Antonio that she went upstairs to apologize. She opened his door and found him masturbating on his bed. She then said, "Antonio, when you're finished with your homework, come down and talk to me."
