80-year old man

A 80-year-old sees his doctor. The latter asked him how things are going.

"This is a true story. I have a friend who is a keen hunter, he never missed a season. One day while he went hunting and he was late,  instead of taking his gun, he took his umbrella.

"No," replied the old man puzzled.
"Well the bear fell dead at his feet!"
"That's impossible!" The old man rose up. "Somebody had shoot the bear in his place ..."
"This is exactly where I wanted to come ..."
