The Wipe

There were two truck drivers in a truck riding down the interstate when one of them told the other one he had to take a dump. Since they were on the road and there were no truck stops for miles, he decided to stop the truck and go behind a bush and do his business but there was only one problem...he didnt have any toilet paper.He asked his partner if he had some paper.He didn't have any paper, but suggested that his friend wipe with a dollar. The man agreed and went behind the bush and handled his business. He came from behind the bush with poop all over his hand so his partner asked him what happened and he replied,"Do you know how hard it is to wipe your ass with four quarters?"
