How often are you like, "What happened to MC Skat Kat?" Constantly, right? Well, we're about to find out on tonight's Dancing With the Stars. Paula Abdul's legendary co-star from her video for "Opposites Attract" (she's a person; he's a cat: classic opposites) will be part of a four-song medley she'll be performing. Last night, after the episode of Dancing With the Stars she guest-judged, she joked: "Someone is coming out of retirement. I've been rehearsing with him, and I can't understand his dance moves. He's all over the place. I told him he needs to get some rhythm because I can't keep up." Give the man a break, in cat years he's probably like 200 years old.
