It should come as no surprise to anyone that such a popular show would have imitators. So far my two favorites have not made the primetime schedule yet, but are still being considered for production.
Dancing With SARS: A gaggle of B list celebrities and their dance trainer partners are infected with the SARS virus and set loose on the dance floor. The last couple standing wins. Created by Horace McCoy and Josef Mengele.
Dancing With The Czars: A succession of celebrity dance couples do routines of increasing opulence, decadence, and irresponsibility, until the finale when the audience rises up, takes the winners down to the basement, and shoots them.
Until those reach the air, hey, at least "Chuck" is back on.
PS: a big hello to Bruce Ray!
