"The Worst Thing" joke

Three guys are out hunting and sitting around the evening campfire exchanging their worst experiences.

The first guy says the worst thing that ever happened to him was, he was up on a scaffold 7 stories high washing windows when the scaffold collapsed and he fell, breaking every bone in his body and he was hospitalized for six months.

The second guy says the worst thing that ever happened to him was, he was hitch-hiking and a Greyhound bus ran over him, breaking his back and he wound up in the hospital for nearly a year.

The 3rd guy was not saying anything, so one of the others asked him about his worst experience.

He said, "Well, I'll tell you about the second worst thing that ever happened to me, I was out hunting one time and I had to take a shit, so I stepped behind a tree, dropped my trousers, and crouched down into *the* position."

"Yeah? what happened next?" asks his friend.

"I got a little too close to the ground and -- WHAM -- a bear trap snapped shut on my testicles."

One of the other guys said, "God! If that was the second worst, what in the world was the worst?"

He calmly replied, "Oh, that would be when I reached the end of the chain. . . "
