I fell at a stoplight when I was already completely stopped. Tried maneuvering away from the front car to get a split second extra to clip in for when the light turned green. Flailed around on the asphalt until some dude got out of his car to help me unclip.

Then, at the very next stoplight, in front of I'm sure most of the same cars, I did the same exact thing.

Bet ya can't top that for embarrassing.
