oh man, we did that at williamsville north after swim practice
apparently we were all spending so long in the lockerroom so our female coach came in to see what was going on...some guy named scott was already sliding in the direction of the door, took a look at our coach walking in, flipped over onto his belly, lost control and smashed into the wall right next to the door, his bare ass directly below her...could've been worse...he could've landed spread eagle on his back instead
that was the last time we did that
