Promo for January

This episode has been called The Diamond in the Rough by EOnline, ("The Diamond on the Rough," is going to take some well-meaning jabs at reality dancing competitions. - EOnline) but it's being listed as The Doll in the Derby on YouTube. I'm not sure which is right, but I'm fairly certain it's The Diamond in the Rough. (Plus, I don't see any derby girls.) Tipster: geraghtyvl
