There's Must See TV this Thursday night and it's called The Colbert Report. Democratic presidential candidate Hillary Clinton will be Stephen Colbert's guest that night. At least, that's the word according to MSNBC's Chris Matthews. He sort-of blurted out the news last night before Colbert's or Clinton's people had a chance to make the formal announcement. Variety contacted a source with Colbert's show and confirmed the news.

Of course she's appearing on the show as part of her push for votes in next week's Pennsylvania primary, but damn. That's gonna be good. Hillary Clinton is considered the devil by many conservatives such as Limbaugh and O'Reilly, and will probably be treated as such by Colbert. But she's a sharp woman and will probably take him down pretty swiftly. If she does well, it could give her a bump just like hear appearance on SNL did.

Colbert is in Pennsylvania for the primary. So far, Clinton's opponent, Barack Obama, has denied Colbert's request to appear on the show. Instead, Obama's wife Michelle will be a guest tonight.
