Pretty decent version of the mud game starting around 14:00.

This reminds me of Truth or Consequences if it had been made now. Only thing missing: Bob Barker laughing himself silly watching people do just about anything for a check.

Parenthetically, even out there, the 'mud' looks to have been trucked in from an art supply store. Wonders.

There's one really awesome chick who totally immerse herself in the mud.

Nice find! Couple of those girls aren't playing around!
