I was building this pump track near a bees nest, and I was just about to get on my bmx to go home. I had a shovel in one hand, and one end of the handlebars in the other, when an exceptionally large and angry bee decided it didn't like me. So I dropped the shovel, and proceeded to sprint along the road - with the killer bee hot on my tail.
I was running really fast, still with only one hand on the bars, but couldn't get on the bike because I was busy swatting away the bee with my other hand. After about 200 metres of flat out running the bee was still just as angry as when I started, and wouldn't go away, so I stopped swatting and reached desperately for the other end of the handlebar... and missed. My hand had gone clear over the handlebar, and I tripped, falling on my ribs onto the centre of the bars. I was doing a kind of one-hand-superman thing, trying to steer with my chest, when I got the wobbles and the bars crossed up, spitting me flat on my face onto the road. This was followed by a rather nasty thump on my back which was the bike landing on me... and then just as I started to shakily get up, the buzzing noise began again.
Worst day ever.
