Bill Nye the Dancing Guy

Seeing Bill Nye on Dancing With the Stars made me remember there was a Stargate Atlantis/Dancing With the Stars crossover. John was security for the show. Rodney was paired up with Cheryl Burke. The Wraith attack during an episode. Rodney, John, Lacey Schwimmer and Maksim Chmerkovskiy ended up at the same place. Lacey and Maks team up to use dance moves to battle a Wraith. Cheryl isn't happy that she got left behind.

Thanks for your help.
