Thanks for the harmonica you gave me for Christmas," Little Johnny said to his uncle the first time he saw him after the holidays. "It's the best Christmas present I ever got."

"That's great," smiled his uncle. "Have you learned how to play it yet?"

"Oh, I don't play it," Little Johnny said. "My mom gives me a dollar a day not to play it during the day and my dad gives me five dollars a week not to play it at night."
