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,
he 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."

"Exactly, that's kind of what I'm getting at," replied the doctor.
