This isn't your normal shave though. Colbert tries out a few looks before eventually revealing his clean-shaven face. "I'll miss you, old friend," he says to his beard trimmings. "But I'll never forget our time together."
While the beard had to go, the show's social networking sites had to be launched. You can now follow and like TheLate Show with Stephen Colbert on Twitter and Facebook.
How do you think Colbert will do as David Letterman's replacement?
