ok, I'll share a non-bike but riding story... the horse mention reminded me of it.

When I was a kid, I took riding lessons (horse) for years. A friend and I were hanging out early one day at the barn, and we noticed the shetland pony in the pasture. Of course we thought we were great riders and the pony would be docile and happy to oblige us. We bridled up the pony, and I jumped on (bareback). The shetland would have none of it and promptly bucked me off.

So, I say with pride, I have been bucked off a Shetland pony!

The duck story was great!
