An 80-year-old man went to his doctor for his annual check-up. The doctor asks him how he's feeling. The 80-year-old says, "I've never felt better. I now have a 20 year-old bride who is pregnant with my child.What do you think about that?"
The doctor considers his question for a minute and then begins. "I have an older friend, much like you, who is an avid trophy hunter and never misses a season. One day, when he was going out hunting, he was in a bit of a hurry and accidentally picked up his walking cane instead of his gun. When he got to the creek, he saw a prime beaver sitting beside the stream of water. He raised his cane and went 'bang, bang'. Suddenly, two shots rang out and the beaver fell over dead. What do you think of that?"
The 80-year-old said, "I'd say somebody else pumped a couple of rounds into that beaver."
The doctor replied, "My point exactly."
