Who shot the beaver?

A 90-year-old man said to his doctor, "I've never felt better. I have an 18-year-old bride who is pregnant with my child. What do you think about that?"

The doctor considered his question for a minute and then said, "I have an elderly friend who is a hunter and never misses a season.
One day when he was going out in a bit of a hurry, he accidentally picked up his umbrella instead of his gun. When he got to the Creek, he saw a beaver sitting beside the stream. He raised his umbrella and went, 'bang, bang' and the beaver fell dead. What do you think of that?"

The 90-year-old said, "I'd say somebody else shot that beaver."

The doctor replied, "My point exactly."
