An 88-year old man came to the hospital and said to the doctor, “Doctor, my 18 year old wife is pregnant with my child.”

The doctor paused and said, “There was a master bear shooter in a village. He never missed a shot.

But one day he was in a hurry, and took his umbrella instead of his rifle by mistake.

When he encountered a bear, he still didn’t realize his mistake and pointed the umbrella and shot the bear.

The bear lay dead with a bullet in his heart!”

The old man said, “That’s stupid! The bullet must have been shot by another person.”

“That’s exactly right,” said the doctor.
