Shooting Blanks

The 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. Then 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".
