Little Johnny sees that his friend at school has a new watch so he asks him how he got it.
"I waited until I heard the bedsprings squeaking in my folk's bedroom and then I ran in. My father gave me a watch to get rid of me.", replied the little friend.
Little Johnny, thinking that this was a cool idea waited that night until he heard the bedsprings squeaking rhythmically and then ran into his folk's bedroom.
"What do you want!", asked the father gruffly.
"I want a watch!", said Johnny.
"Well sit down and shut up!", replied the father.
