Johnny Grades His Mom

One day little Johnny asked his mother how old she was and she told him that
little boys didn't ask ladies how old they were.  Some time later, he asked
his mother how much she weighed and she told him that little boys didn't ask
ladies how much they weighed.  Then he asked his mother why she and his daddy
had gotten a divorce and the mother told him that little boys didn't ask ladies
personal questions like that.

Later that day the Johnny was playing with a friend and told the friend that
his mother wouldn't tell him how old she was or how much she weighed or anything.
His friend told him that all he had to do was look on his mother's driver's
license and he could find out anything he wanted to know.

So the little Johnny went home and looked on his mother's drivers license and
then went and told his mother he knew how old she was and told her she was 30
years old.  Then he told her that he knew how much she weighed and told her
she weighed 125 lbs.  Then he told her he knew why she had gotten a divorce
because she had gotten an 'F' in sex!
