When I was young I had a bike with a front carrier (Moulton Deluxe). Riding into the wind, head down, I rode into a parked car and ended up on the bonnet (hood). The carrier went straight into the radiator, and as a neighbour pulled me off there was a nice trickle of green water coming from the car.

I once bonked so badly that a five year old on a tiny bike out with his mum decided to race me and there was nothing I could do about it.

Last year in Chamonix I had just descended a very steep and long trail, hopped off at the bottom, looked back up the hill for my g/f, stepped back and put my leg on the red hot rear disc. I swear it went Hiss as it branded a nice little crescent mark in me. She laughed as I was hopping around. We are no longer together.
