Joe Scarborough was on Jimmy Fallon's show last Wednesday night, and he wanted to work through his mid-life crisis by playing some rock'n'roll guitar. So he played an Elvis Costello song about desperately wanting to get laid, with the Roots.

Costello has done a thing or two to tarnish his own reputation in his later years—his Sundance Channel chat show is pretty embarrassing. And that stupid hat! But the spectacle of seeing a Gingrichite ex-congressman who once represented the murderer of an abortion doctor playing "Mystery Dance" and actually crossing his legs mid-song has killed rock'n'roll again, for the thousandth time. It's like when we found out that George W. Bush likes Alejandro Escovedo.
