Heh. Same sort of thing happened to me about a month ago. I had taken the wheels to a LBS for new tubeless tires and must not have put the rear one back on tight enough. Near the end of my ride I went to start up from a green light and the rear wheel actually came out of the dropout and locked up the chain. I nearly flipped over the bars.
Maybe we should kick each others' butts.
