Little Johnny asks his mother how old she is, and she replies, "Gentlemen don't ask ladies that question."

Johnny then asks his mother how much she weighs.

Again, she replies, "Gentlemen don't ask ladies that question."
...
Then, Johnny asks, "Why did Daddy leave you?"

His mother shouts, "Go to your room, young man!"

On the way to his room, Johnny trips over his mother's purse and her driver's license falls out. He glances at it and then says with a grin, "I know all about you now...You're 36 years old, weigh 127 pounds, and Daddy left you because you got an 'F' in sex!"
