In June of 2011, The Colbert Report aired a three part series called 2000 and 1...and 1: A Rock Odyssey (if you watch, you'll know why I wrote the title in such a long, odd, broken up way). The series follows Stephen Colbert on his quest to record a follow up to his 1980s song "Charlene (I'm Right Behind You)". He enlists the help of Jack White, and the deadpan hilarity ensues. I haven't laughed so much since the NPR Muppets interview with Jason Segel.
The best part of this series (though) is the outtake aptly titled "Catholic Throwdown". It features Jack White and Stephen Colbert trying to out-Catholic each other. It's priceless.
