Here are some of the Fix's favorite moments with "Stephen Colbert" -- on the Report, his prior life at "The Daily Show," and a few brushes with actual government.
Warning: As you might imagine, some of these clips have salty language.
When Jon Stewart and Colbert burst out laughing on the Daily Show
Some of the best moments Colbert had on Comedy Central involved Stewart -- especially when they couldn't help but bursting out in laughter at the absurdity of what they were doing. Enjoy this old Daily Show clip about the British monarchy. (Side note: Both Stewart and Colbert look unbelievably young.)
The glory of 'Downton Abbey' actors re-enacting 'Breaking Bad'
That time Colbert danced with everyone to the dulcet tones of Daft Punk
Including Henry Kissinger.
The only reason you think this is a word? Stephen Colbert.
The fact that no one loved being on the Colbert Report more than James Franco
Every single time he went on, he had this ridiculous grin on his face the entire time. This may have been because he is James Franco, or it might be because he was so excited about the possibility of a Tolkien showdown.
When Colbert talked about his mom
This moment was heartbreaking. In 2013, Colbert's mother died, and he spent a few moments talking about her on the Report -- as Stephen Colbert, the man we're finally going to see more of on his new show, not "Stephen Colbert," who will disappear tonight.
When Colbert did a bit at the White House Correspondents' Dinner
It was 2006, and unlike most comedic bits at the White House Correspondents' Dinner, people had lots of feelings about it. Not only that; it was memorable.
When Stephen Colbert testified in front of a House subcommittee
As a fictional character. American government is great.
The Colbert super PAC
Colbert's super PAC and Ham Rove made many memorable appearances on the Report -- and managed to teach people more about campaign finance than many other news outlets. The best segment featuring the super PAC may have been the one where Colbert was forced to say aloud some of the names of people who had donated to his PAC.
When Stephen Colbert managed to make a weirder campaign ad than Herman Cain
He introduced us to Johnny Cummings -- mayor of Vicco, Ky.
