"OH SIT!" - (8:00-9:00 p.m. ET)

"Havana Brown" (TV-PG, DL) (HDTV)

HAVANA BROWN IS THE MUSICAL GUEST - In this fun, high-stakes, high-octane musical chairs competition featuring new obstacles and bridges, water rounds, mechanical rounds and slick zones, 12 thrill-seeking daredevils who will race head-to-head through five physically demanding, chair-splitting obstacle course-style eliminations as they each compete to claim a chair - all to the sounds of a live band. At the end of the hour, only one contestant will be left sitting triumphant to seize the cash prize and the title of OH SIT! champion. The show is hosted by Jamie Kennedy ("The Ghost Whisperer") and actress/television host Jessi Cruickshank ("MTV Live"). Adding to the fun, Tanika Ray ("Extra") will be in the trenches with the contestants both on and off the track, and will add color commentary from the sidelines as the action unfolds. Havana Brown ("Big Banana," "We Run the Night") is the musical guest. The episode was directed by Glenn Weiss (#117).
