Years ago on Wide World Of Sports, I recall an event where people would slide on a leather pad behind a car. They would wear a leather apron of sorts on their backside, hold on to a rear bumper while that car barreled down a racetrack, then let go. The winner was the one that slid the furthest. They’d never let that happen today.
Maybe if they had some of that special coating from Sparky in "Christmas Vacation".
