ewww .. what a picture!
Tho it reminds me somewhat of my grandmother... when I was little (must have been 6 or 7) she broke her leg, and she came to stay at our house until she was able to be back up and about enough to take care of herself full-time. One night she got tired of the cast, which she said itched like hell. So in the middle of the night she shuffled into the kitchen and tried to saw it off with a pizza cutter. Unfortunately it was dull & she barely scratched it. This guy obviously had a better success rate!
