A 90-year old man said to his doctor, "Doc, I've never felt better! I have an 18-year old beautiful bride who is pregnant with my child. What do you think of that?"
The doctor paused, thought about it a moment, and then replied, "I have an elderly friend who is a hunter and never misses a season. One day he was in a hurry and picked up his umbrella instead of his gun by mistake. When he got to the creek, he saw a beaver. He raised his umbrella and went "bang, bang, bang", and the beaver fell dead. What do you think of that?"
The 90-year old said, "I'd say somebody else shot the beaver." The doctor said, "My point exactly."
