This was quite a few years ago, but a friend and I were home on leave at the same time and we decide it would be a good idea to go the large toy store that was nearby. They had these long, wide aisles in the store. We grabbed a couple of those toy horsey balls and proceeded to race up and the aisle. Much to the chagrin of management and to the embarrassment of his then girlfriend. It seemed like the thing to do at the time. It also helps that we're easily amused.
