Ulterior Motives

Billy's dad was away on a business trip. So he wanted to sleep with his mother. The first night she refused. The second night she refused again. On the third night she decided to let him lay there for a while and take him to bed when he fell asleep.

So Billy put on his pajamas and jumped into bed on his father's side.

With both his hands behind his head, he said to his mother: "With Christmas approaching, don't you think it would be a good idea if we buy Billy a bicycle?"
