A good few years back when I was on a ride with some friends across Woodbury Common we thought we'd take a short cut. We ended up trying to ride on some almost un-rideable trails covered in gorse. Of course I had to go and fall off to the side of the trail landing in a large patch of gorse.
As I wasn't wearing gloves I couldn't put my hands out to push myself back up again and so had to call my friend to help me out… cue second problem… I was just wearing a pair of baggy shorts and loose boxers underneath. As my friend pulled me to my feet I felt a sharp prick to the old bean bag and realised that a sprig of gorse was up my shorts and nesting on my sack like a needle about to pierce a balloon.
Not so much stupid but very painful and embarassing.
