I once fell standing. Yup. I had stopped to wait for a biking buddy who had been hailed by a passing car. So, I waited about 50 feet up the road and chose that moment to fish a butterscotch candy out of my rear pack. I had unclipped my left foot which was FIRMLY PLANTED ON THE GROUND. Somehow, when I reached back, my right knee twanged a little and I shifted it and then the next thing I knew...I was falling on my right side. Oh...Yeah.. no breeze, no wind, no wind sheer, no nothing. Three cars witnessed this hideousness and I had people rushing to help. Those same 3 cars had bikes mounted on them and I'm sure that every single one of those people thought I had had a heart attack: the only reason a cyclist would suddenly pitch over STANDING STILL . I was almost willing to fake a heart attack just to avoid the humiliation.
The good thing, of course, was that everyone had their own story of bike humiliation to tell; all we needed was a campfire and some hot dogs to make it complete.
