Watch Stephen Colbert Gear Up for 'Late Show' in First Promo Vid

"Welcome to the Internet," Colbert tells fans in new video. "Good news: I still exist"

It's been six long months since Stephen Colbert left The Colbert Report – and just two weeks since David Letterman retired from late night – but the future Late Show host returned to the public eye today with a new video trumpeting the near-arrival of his late-night program (and the disposal of his "Colbeard").

"Welcome to the Internet. Good news: I still exist," Colbert tells fans after six months of not talking into the camera. "My show went off the air in December and you have not seen me much since then, unless, of course, you're my family or the clerk at my local Rite-Aid." Colbert then catches us up on his long layoff, including the fact that he didn't lose any weight like he planned ("a plot twist I didn't expect") and the salt-and-pepper beard he found by the highway.

"As much as I enjoyed being incognito, now that we're gearing up for the beginning of the Late Show, I need to be more cognito," Colbert says. “Plus, CBS is making me shave it off because Tom Selleck's mustache has a non-compete clause," a nod to the network's Blue Bloods star. Colbert then spends the next three minutes hilariously shaving his "Colbeard" while giving names to all the different facial hairstyles with each brush of the razor, like the "half-Wolverine."

Because Colbert's Late Show is in pre-production, that means he doesn't yet have a production budget, so instead of simply playing Green Day's "Good Riddance (Time of Your Life)" to soundtrack his beard escapades, Colbert is forced to use an instrumental track of the song accompanied by the lyrics to "Camptown Races."

While Colbert doesn't have a budget yet, he does have a boatload of new social media: On Wednesday, The Late Show With Stephen Colbert unveiled its logo, its Facebook, its Twitter, its YouTube, an official website, an app (Colbr) and even a podcast. ("Is The Late Show Podcast the New Serial? Or is it... MURDER?!, the Late Show Twitter asks.) That should provide fans plenty of content to explore in the three months until Colbert makes his CBS late night debut on September 8th.

"Say what you will about the Internet, I think it's here to stay!" Colbert said in a statement (via New York Times). "Launching ColbertLateShow.com puts me in the same league as Google.com, Facebook.com and ferretfancier.blogspot.com!"
