Little Johnny, always curious about the world, once asked his father a question that left his mother eavesdropping from the kitchen. “Dad, why do grown-ups like to exercise in bed?”

Without skipping a beat, his father replied, “Well, Johnny, it makes grown-ups happy.”

Intrigued, Johnny expressed his desire to be happy too. But his father explained that he would have to wait until he became a grown-up himself.

“But who will exercise with me when I grow up?” Johnny questioned.

With a smile, his father replied, “Hopefully, when you get married, it will be your wife.”

Confused, Johnny brought up their neighbor Sally. “But Dad, how come our neighbor Sally exercises with you?”

Worried, Johnny’s mother rushed out of the kitchen, and an ambulance arrived 10 minutes later.
