My most interestingly shaped one also has the most wussy story: I cut myself in front of an annoying customer, trying to cut the ziptie off of a set of juggling sticks, right when she said "Be careful! Don't cut yourself!"
I didn't give her the satisfaction of knowing I had cut myself, but pinched the blade into the cut to keep it from bleeding, calmly had one of the other cashiers finish her transaction, and went into the back room to pull the blade out of my hand, at which point it started bleeding. A lot. I probably should have gotten stitches, but meh. Nothing a little bandaid wouldn't fix.
