Once when I was in my basement watching Episode III I suddenly decided it would be a good idea to start acting out all the lightsaber action in the movie. Well when I was acting out the part where Anakin & Obi-Wan were killing the driods in the elevator. While I was swinging away I forgot how low the basement ceiling is. So I was swinging my FX when all of a sudden SMASH! I smashed a light bulb! Tiny shards of glass rained upon me. I spent about 10 min picking up the glass. I'm never doing that again. ;)
