An 80-year-old man went to his doctor for his annual checkup. The
doctor asks him how he's feeling. The 80-year-old says,
"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 considers his question for a minute and says, "I have
a friend who is an avid 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 rather than his gun.
When he got to the creek, he saw a prime beaver sitting beside the stream of water. He raised his umbrella and went, "Bang, bang", and the beaver fell over dead. What do you think of that?"

The 80-year-old said, "I'd say somebody else shot that beaver."
The doctor replied, "My point exactly."
