The Wrong Birthday: A man once went to a birthday party for his friend's son. He arrived late and didn't know the boy very well, so he asked him how old he was. The boy replied, "I'm four." The man thought this seemed a little old for the boy's size, so he asked the boy's mother how old he really was. She replied, "He's two." The man then turned to the boy and said, "You're not four, you're two!" The boy looked at him and replied, "I know, but I'm going to be four tomorrow!"
