Who shot the beaver?

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

The doctor 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 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."
