About a year and a half ago when I first bought my beater 10 speed, I was riding and I noticed a slight clicking in the drivechain. Being the idiot I am I looked down for like 10 seconds to see if I could hear where it was coming from, I consequently hit a fire hydrant. I got thrown over my handle bars but since i wasn't going super fast just landed on my feet. Some guy then rode by and gave me the stink eye.

Also more recently on my first ride on the new frame I had bought I was trackstanding at an intersection. While doing this I caught my clip stuck on the front tire because the overlap was much larger than I expected. I went face first into the asphalt and some bus driver told me it was the best thing he'd seen all day.
