Who shot the bear

An 90 old man was having his annual checkup and the doctor asked him how he felt. "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 while, then replied, "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 a gun." The doctor continued, "So he was in the jungle suddenly a 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 next?" the doctor queried.
Dumbfounded, the old man replied "No."
The doctor said, "The bear dropped dead in front of him!"
"That's impossible!" exclaimed the old man. "Someone else must have shot that bear."
"That's kind of what I'm getting at..." replied the doctor.
