First man: "There's a guy who lives up the street from me who used to work in construction. One day last year his hand got run over by a bulldozer. Whatever those doctors did, it's really amazing - today he's a concert pianist."

Second man: "That's nothing. I knew a guy in college - laziest bum I ever knew. He was really fat and out of shape. He was trying to hitch a ride one day and got hit by a truck. Broke nearly every damn bone in his body. Somehow they put him back together better than he was before. Now he's a triathlete and he's planning to try out for the Olympics."

Third man: "Yeah, well I knew this poor retarded kid. He couldn't do a whole lot, but someone at the dynamite factory got charitable and gave him a job as a stockboy. He was working in the warehouse one day and got locked in. It was dark and he couldn't find the door. Not being too bright, he lit a match to try to find his way. The whole place exploded. All they could find of him was a few fingers and his eyebrows. From that little bit they were able to put him back together and today that kid is the President of the USA".
