Well there was this one time when a freind of mine needed some extra money while he was in college, so he decided to sell knive sets (like the ones that get advertised on TV at 3am).

So in order to prepare himself for his new job, once he got his demo set, he had a bunch of us come over so he could practice his sales pitch. I was there with my best friend, NOT the knife sales guy, and after witnessing my friend Jim do his sales pitch, my friend Darren grabs one of the knives and attempts to make a cut with it, cutting off the tip of Jim's thumb.

We didn't realize it at first, but noticed that Jim had left the group for a while, we found him soaking his thumb in the bathroom sink, full of ice.
