Unbearable.

 An 80 year old man was having his annual checkup when the doctor asked how he was feeling.

"I've never been better!" he boasted. "I've got an 18 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 accidentally grabbed his umbrella instead of his gun. So he was in the woods and suddenly a grizzly bear appeared in front of him! He raised his umbrella, pointed it at the bear and squeezed the handle. And do you know what happened?"

Dumbfounded, the old man replied, "No, what?"

The doctor continued, "The bear dropped dead in front of him."

"That's impossible!" exclaimed the old man. "Someone else must have shot the bear."

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