I had a pretty embarassing moment at centerparks a few months ago. I was bored so i went out on the bmx to a speedbump neer the main pool complex, Loads of people all around. I was showing off a bit with all the 180s and x-ups and had my jeans reall low. So of course they fell right down and went into my back wheel, stoped me dead and i flew right over the bars. So i was stuck with trousers down, bmx on top of me infront of about 70 people. I just sat there for about a minute, but it felt like an hour.
Bad times. But its just funny now!
