I was told I would fall 3 times when I first went clipless - that's the average. I have fallen twice so far and of course in front of a crowd of people and in that comical slow motion sort of way. I keep waiting for my 3rd fall. I've also seen it happen to others several times.

Best story I heard about a clipless mishap was from a gentleman cyclist in a crowded intersection at a stoplight who, in the slow agonizing process of falling over, somehow managed to hook his shorts onto the nose of his saddle, thereby suffering the humiliation of, not only the fall, but the subsequent "de-panting". And to make matters worse (as if they could get any worse than this) he writhed around on the ground for what seemed like an inordinate amount of time trying to free himself of this debacle - his shoe was *stuck* to the pedal. He eventually had to unbuckle his shoe and remove his foot in order to untwist himself from the bike - and of course all the while he's butt naked. He said there were quite a few whistles and honks from the motorists and onlookers.
