A man walked into the dentist office to have a tooth removed. The dentist asked him if he wanted some Novocaine to kill the pain. The man told him he didn't need it. The dentist pulled the tooth and the guy never flinched. The dentist remarked that he must be pretty tough and they guy replied "I've only been hurt once in my life. I was hunting in the woods one day and had to go, so I dropped my pants and squatted down to do my business and didn't see a bear trap."
The dentist says "Wow, that must have hurt" to which the man replied "it wasn't too bad. What was bad is when I hit the end of that chain."
