102 year old man is having his annual checkup. The doctor says "how are you feeling?".
"I've never felt better," he replies. "I've got an nineteen year old bride who's pregnant with my child. What do you think about that?"
The doctor thinks for a moment and says, "Let me tell you a story. I know a guy who's an avid hunter. He never misses a season but one day he's in a bit of a hurry and accidentally grabs his umbrella instead of his gun. So, he's walking in the woods near a creek and suddenly spots a beaver in some brush in front of him. He raises his umbrella, points it at the beaver, squeezes the handle, and BAM! the beaver drops dead in front of him."
"That's impossible," said the old man in disbelief, "someone else must have shot that beaver!"
"Exactly", said the doctor.
