I was 12 when Jackass first hit the screens and immediately decided to ignore all those warnings and attempt to jump my mountain bike off a home-made ramp. Unsurprisingly, the ramp immediately collapsed under my weight, locked my front wheel and sent me sailing over the handle bars, just like the boys on the show. Unlike those guys, I hit the ground and burst into tears: this is when I learnt that falling off isn’t funny - it’s painful and dumb.
