"Thanks for the harmonica you gave me for Christmas," Little Johnny said to his Uncle Rodney, the first time he saw him after the holidays. "It's the best Christmas present I ever got."
"That's great," said his Uncle Rodney. "Do you know how to play it?"
"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."
