The bloke stood in front of the kwak trying to do a reverse burnout was the funniest for me (1min 05 sec) Why whould you, I mean really, you've gotta think what would happen if it went wrong .............. which he obviously didn't and it so dramatically did! ha ha (gets funnier every time I watch it)
Some of those looked painful and expensive - funny though. I think I remember doing some similar sort of stuff myself. No bugger videoed mine though! :(
