Little Johnny

The class's instruction was to bring a "show and tell" to school for the following day.
When it was little Johnny's turn, he proudly held up a light bulb.

When the teacher asked him what it was for, he said. "my Dad eats light bulbs!" Everyone laughed and the teacher admonished him, saying "that can't be!"

Johnny said it was true, he said, "it is true, I heard my Dad say to Mom, turn the lights out and I'll eat it for you honey!"
