Stephen Colbert is a man of action, a man who gets things done, a man who enjoys the high of a good felt-tip marker. In preparation for taking over as host of The Late Show Stephen took it upon himself to write the show's new theme song. Sure, he could have hired somebody with musical talent to do the job, but that's not how one saves money and if he'd been foolish enough to do that we might not have gotten a lyrical gem like: 

"My name's Stephen Colbert from my head down to my feet, where I keep my toe."

Now that that's out of the way, all he's gotta do is harvest those clone organs, get some oxy, and it should be smooth sailing into the calm waters of late-night.
