Three men were sitting around the fire, drinking beer and telling stories.
 After a while, one of the men looked at the others and challenged them to
 describe the worst pain they had ever experienced.
 
 "Well," said the first, "the worst pain I ever felt was 2 years ago. I was
 helping a friend to load a refrigerator into his rental truck, when the dolly
 slipped out from under it, and the refrigerator fell over onto me, crushing
 both of my legs and most of my ribs."
 
 "That's nothing," claimed the second. "One day, I was riding my motorcycle
 through town, and I ran a red light. A bus was coming the other way, and I was
 hit by the bus, thrown into the air, where I skipped off the roof of a car,
 and ended up flying through an 8 foot plate glass window. I broke both arms,
 both legs, most of my ribs, and had about 8000 cuts all over my body from the
 glass."
 
 Both men then looked at the third, who had been sitting very quietly during
 both stories. "Well, what's the worst pain you ever felt?"
 
 The third man looked at both the others, shuddered, and said, "One day, I was
 out hunting with my buddies, and I had to go to the bathroom. So, I squatted
 down over a log, and while I was doing that, I sprung a bear trap that snapped
 closed around my testicles."
 
 Both the other men began to squirm, and they both agreed loudly that that had
 to be the worst pain in the world.
 
 The third man just slowly shook his head, and said, "That's nothing compared
 to when I came to the end of the chain..."
