The Tough Lumberjack
The doctor told the nurse to prepare a dose of pain killer.
"Don't bother Doc", said the man. "I've been through a lot worse".
"More painful than this" the doctor asked?
"I'll tell you about the second most painful accident I ever had. I was working in the woods one day and had to take a crap so I dropped my pants and squatted down without looking. I tripped a bear trap and BAM, the thing snapped shut on my balls"!
The doctor winced and said "That's terrible. But if that's only the second, what could be worse"?
The lumber jack replied, "When I jumped up, started to run and came to the end of that chain"!
