Little Johnny was out with his mother. Out of the blue, he asked, "Mommy, how old are you?"
His mother replied, "Honey, women don't talk about their age. You'll learn that as you get older."
Little Johnny then asked, "Mommy, how much do you weigh?"
His mother responded, "That's another thing women don't talk about. You'll learn that too."
Still curious, Little Johnny asked, "Mommy, why did you and Daddy get a divorce?"
His mother, a little annoyed, said, "Honey, that subject hurts me very much. I don't want to talk about it now."
Frustrated, Little Johnny sulked. Later, at a friend's house, he talked about the conversation. His friend suggested, "Just sneak a look at your mom's driver's license. It's like a report card; it tells you everything."
The next time they were out, Little Johnny exclaimed, "Mommy, I know how old you are! You're 32!"
Shocked, his mother asked, "Sweetheart, how do you know that?"
Little Johnny shrugged. "I just know. And I know you weigh 130 pounds."
"Where did you learn that?" his mother asked again.
"I just know," said Little Johnny. "And I know why you and Daddy got a divorce. You got an 'F' in sex."
