The Colbert Report has caused quite a stir after Wednesday and Thursday  tapings for the popular show were cancelled at the last moment.  The show's audience department called it "unforeseen circumstances" but sources say it will be up and running soon.  Colbert's website is now listing reruns and Colbert himself has been quiet on Twitter since Wednesday afternoon since  tweeting a presidential joke.  Fans had actually starting lining up outside the show's Manhattan studios and some were even in their seats when an email was issued by Comedy Central regarding the cancellation!
