In reply to Annoying Twit:
Once, bouldering indoors, I leapt for the final jug to complete the problem just above and to the right of my (it was actually a high pop, more than proper dyno), caught the hold with one hand, carried on upwards and to the right past the hold, lost grip on the hold, after pivoting round it somewhat and fell face first (think skydiver long bofore they open the 'chute) onto the mats about 4m below.
It was glorious but thinking back on it i can't see how the laws of physics were obeyed during it... No injuries though.
