When it debuted: 2010
Segment lowlight: The time Secretariat went on Regis and Kelly.
Craig Ferguson embraces the role of the underdog. A number of his bits are based on the idea that, as the host of a low-budget show, he has to take numerous cost-cutting measures. One such gag originated as a spoof of the movie Secretariat, and became a hallmark of the show.
While Ferguson was mocking the film in 2010, a horse (clearly two actors under a blanket) jumped out and started dancing to an obnoxious club beat. The bit is nothing more than the horse dancing. That's it. Sometimes it goes on for over two minutes. Here is a 25-minute video chronicling the history of this overused, tired gag. If you have time to watch the whole thing, you should really look into a hobby for your future.
