I'm chickening out - I'm bored with the show tonight, so I'm using the synopsis from Television Without Pity:
Tonight's first game involves the women surfing and the men hula dancing. Kathy fails to stand on a surfboard for five seconds, so they don't win any money. Erik has a chance to make up for her failure by standing on a surfboard for ten seconds, but he can't do it. Then all four of them get to compete for one final exemption that will guarantee a spot in the final round. First, they pair up to do math puzzles, and Kathy and Erik win. Then those two square off in a series of SAT-style logic puzzles, and Erik wins with a three-second faster time. Finally, Erik has to complete a game of concentration using a deck of cards in a mystery location before Kathy, Michael, or Frederique finds him. A security guard weirdly detains Frederique, and Erik gets the exemption. And then Michael gets executed.

The pot is still at $151,000 since no money was won in this episode.
