The show: Foxs Celebrity Duets, where non-singing celebrities are paired with established musicians to compete for viewer votes.
The cast: Chris Jericho, Lea Thompson, Carly Patterson, Cheech Marin, Jai Rodriguez, Hal Sparks, Lucy Lawless and Alfonso Ribeiro (pictured).
The prize: A donation to the winners favorite charity.
Sample challenge: Poor Lucy Lawless had to strain to be heard over partner Michael Bolton during their performance of Time, Love and Tenderness. The horror, the horror.
Did it work? One of the better shows to watch, the 2006 series didnt catch on enough to get renewed for a second season. It did bring Alfonso Ribeiro -- and his Fresh Prince of Bel Air dance -- some short-lived goodwill.
