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

"johnny"…it reminds me the song of Yemi Alade...
