My best clipless fall (there have been 3, but this one is worthy of a tale):

Commuting home from work. I had been having trouble with my pedals (bearings coming out of adjustment,) but was pretty sure I'd fixed them. There is one long hill on my route home, and it's enough to really slow me down. I'm just starting up that hill, when my right pedal started dragging. "Crap." I think "There goes the bearing adjsutment again. Well, I'll look at it at the top of the hill." I kept chuigging up that hill.

A little while later (still on the hill) I realized that my right pedal was really starting to bind up, and my right shoe felt funny. I (belatedly) looked down and realized that my shoelace had gotten wrapped around the pedal axle, and with every stroke, it was winding up more shoelace, like a windlass. I decided to stop, and automatically leaned to the right and tried to unclip my right foot.

Yes, my right foot, the one that was now not only clipped into the pedal, but firmly tied there. I was now leaning right, with my right foot unable to release from the pedal.

I quickly unclipped my left foot, and began flailing my left leg about in a vain attempt to reverse my lean. However, I only managed to halt it, and so I hung there, poised in the most bizarre trackstand ever witnessed by humanity. I probably only held that position for about 5 seconds, but it seemed much longer.

I realized that there was no winning this one, and bowed to the inevitable, flopping over into the grass to my right.

All of this was witnessed by a friend on the local Police Department. He pulled up in his cruiser and asked if I was alright. I said, "As long as you can't literally die of embarassment, I'm fine..."
