So Craig Ferguson's people sent their "Secretariat" to New York and arranged for some cameos on the sets of Manhattan-based TV shows. Actually, it looks like a different horse costume and based on the style of dancing, it's two other guys inside it. Apparently, they couldn't quite get everyone to go along with the joke, which is that when the horse dances through, everyone gets up and does the Secretariat Dance. Regis and Kelly went along with it and so did Katie Couric. The ladies of The View and David Letterman decided to just look annoyed and work against the joke. But it's still a funny piece of video…
