Thanks for the harmonica you gave me for Christmas

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," said his uncle. "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."
