Little Johnny Again
Little Johnny asks his mother how old she is. Her reply is, "Gentlemen don't ask ladies that question."
Johnny then asks his mother how much she weighs. Again the mother's reply is, "Gentlemen don't ask ladies that question."
The boy then asks, "Why did daddy leave you?" To this, the mother says, "you shouldn't ask that" and then sends him to his room.
On the way to his room, the boy trips over his mother's purse. When he picks it up, her driving license falls out.
The boy looks it over and goes back to his mother saying, "I know all about you now. You are 36 years old, weigh 10 stone and daddy left you because you got an 'F' in sex!!!"
