Replying to Pivot/fks thumb

Okay, so the other day I got some new look pivots from rei from some in store credit I had. When I walked back to my car, I was intrigued by the bindings, since I had never had such a nice pair. I started twisting them around, and all of the sudden the fucking thing popped up and latched onto my thumb! My thumb was caught between the thin metal bar and the bottom of the heel piece, and was getting pinched thinner then a pencil. I was freaking out, trying to get the damn thing off. I even set my thumb on the ground and tried kicking the binding down like it was on a pair of skis. It did not work. By this time, a couple of minutes had gone by and my thumb was pale white and bulging twice as big as a large grape on the other side. I was scared shitless. I even thought my thumb was going to have to get amputated or the bindings cut off. I jumped out of my car and ran into a nearby grocery store. I ran into the bathroom and tried running cold water on my had and yanking it out. It didn't work. I then ran around the store asking people for help. Nobody could, and people looked at me like I was crazy. Finally, a fellow skier who had the same thing happen to him knew what to do and plied the bindings off my thumb. Luckily my thumb is not gone and I only suffered a couple blisters, a broken fingernail, and a sprained thumb joint.
