Setting fore to oneself was a punk rocker craze a while back. DOH!

My stupidest moment?> I was using a borrowed vacuum with a shag rug beater attachment. It suddenly stopped and (without unplugging it) I stuck my hand in to remove the blockage. I did...and when it started up again, it caught my hand. I was alone. Had to unplug the damn thing and then extract my hand. No broken bones but I was a lovely shade of purple from my fingertips to my elbow.
If you don't know what it is...
