A lumberjack is in the hospital with a broken arm. Doctor comes in, after the x-rays, and says, "Definitely broken. We need to set the bone so we can put a cast on it, and it's going to hurt. We will give you something for the pain."
Lumberjack looks at him and says, "I've only ever felt pain twice in my life, I don't need anything."
The doctor looks at him incredulously and asks him, "Only twice? What happened?"
"Well, one day I was in the woods and I had to take a crap. So I dropped my pants, squatted down and got my balls caught in a bear trap!"
The doctor, quite astonished by the tale, asks says "Wow, what was the second time?"
"When I reached the end of the chain."
