I think this is the link the OP meant to post.

Another mishap that definitely does not qualify as one that happened when no one was looking. Coming down a slight hill at my college, I picked up a little speed, as I always do. There was a bit of a traffic bottleneck (pedestrians and the occasional bike, not a car area) on the way to my dorm. I was generally nimble enough to weave around the peds without losing much speed, and today was no different, except that there was cyclist coming the opposite way doing the same thing. I moved to left to get out of his path, and, at the same time, he moved to the right (his right, my left). Oops, we both saw that we were still on a collision course, and we both moved back to our original course and, I believe, came close enough to each other that, while our bikes didn't actually touch (at first anyway), our handlebars each connected with the rider of the other bike and knocked us both off, leaving us both dazed and sitting on the ground. Kind of like jousting.
