When I was a rowdier version of myself, I worked as a mechanic at a Sears warehouse. When the warehouse man went on lunch, we would take care of the customers.
One of my drinking buddies and I went back to get somebody's new kitchen appliances with hand trucks. On the way back, we started racing. He did the perfect pit maneuver, and I went sailing up onto some rolls of carpet. Just at that moment of maximum adrenaline and exertion, trying to not damage the goods on the hand truck, the shart struck!
It was unmitigated disaster. I somehow stiff legged through the whole transaction, remaining downwind at all times. Then I retreated to the restroom to do laundry.
