Frozen pitch on a Sunday playing rugby league U16's or something. Sprinting down the wing, past a few only to get to the big fucker who clearly wasn't U16 (let's be honest, every team had one), left foot gets locked into the frozen pitch just as he's about to reach me on my right side. Bang, impact to the right leg. Right leg and body goes down up until the left knee/lower league which is locked into the ground. Fuck that hurt, still can. The knees nicely scarred, also has a blue dot where I was stabbed with a fountain pen.
