My first crash was pretty dull, misjudged a jump over a log (went to do the old push down on the front, the yank up and over the log), ended up hitting the log with the suspension already fully compressed. Ooff, over the handlebars.

My favorite crash: I went over the bars, unclipped, and landed on two feet, gymnast style. The bike went tumbling down the hill (sadly breaking the deraileur hangar).
