We Played Strip Poker

Summary
Mark and Ethan play strip poker, with each player betting their clothes instead of traditional chips, the loser having to strip the amount they bet with. As the two cannot see nor interact with each other, both used their own decks in accordance with the rules. Nearing the end, after losing all of his clothes, Mark goes outside and dives into his pool, with his body floating along the surface. The video then ends with an abrupt jump scare, before cutting back to Mark as he reemerges from the pool and walks off-screen in a crouched position.

Trivia

 * The end scene of Mark crawling out of his pool would later be repurposed as a photo titled "Neanderthalensis Marconius" for one of their Camp Unus Annus skits.
