An 80 year old man was having his annual checkup and the doctor asked him how he was feeling.

"I've never been better!" he boasted. "I've got an eighteen year old bride who's pregnant and having my child! What do you think about that?"
The doctor considered this for a moment, then said, "Let me tell you a story. I knew a guy who was an avid hunter. He never missed a season. But one day went out in a bit of a hurry and he accidentally grabbed his umbrella instead of his gun."
The doctor continued, "So he was in the woods and suddenly a grizzly bear appeared in front of him! He raised up his umbrella, pointed it at the bear and squeezed the handle.
"And do you know what happened?" the doctor queried.
Dumbfounded, the old man replied "No".
The doctor continued, "The bear dropped dead in front of him!"
"That's impossible!" exclaimed the old man. "Someone else must have shot that bear."
"Er, that's kind of what I'm getting at..." replied the doctor.
