I also had a mate who managed to do something similar, in the house matches in school. He was one-on-one with the keeper and managed to knock the ball past him. The ball was rolling into the goal, and if he left it, he would have scored - but he felt the need to catch up with it and boot it, spooning it over the bar from no more than three yards.
Everyone on both teams fell to the floor, pissing themselves laughing. Even our PE teacher was in tears
