2021-05-23 John Marsh goes for a "walk" in the swamp, wearing nothing more than a pair of tiny PVC briefs. After a short slog in thigh deep mud, he steps into a deep mud hole and slowly sinks until he has completely disappeared below the surface of the quaking muck.

After John disappears, the video fades to black, then it fades back in as he wriggles back out of the mud and exposes his mud covered body. That is only the last minute. Most of the clip is the initial sink.
