Well was running across a three lane road that came off a ring-road to get to the car park with my mates, lost my footing whilst running over an island (the road was completley clear), and whilst running halfway across the road my left leg gave way and next thing I knew i was sitting in the middle of a three lane road with my mates on one side of the road p***ing themselves laughing, with me basically dragging myself across the pavement in case any cars were coming!
