Today at Gawker.TV, Andy Richter and George Lopez talk TBS Late Night strategies, Stephen Colbert and Elvis Costello duet, Community goes Mean Girls, "fear boners," and Jason Sudeikis almost becomes a new member of the Always Sunny in Philadelphia gang.

Stephen Colbert and Elvis Costello ended last night's Report with a charming duet. While this is indeed fantastic, it makes us yearn for more episodes of Cotesllo's brilliant talk show Spectacle. Let's make it happen, Sundance Channel!

Saturday Night Live has had a Lion's share of great TV moments during the show's illustrious run. Some of the most memorable moments come from the musical guests.

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.

In other Elvis news, the Elvis that is Costello is, for some reason, going to make a guest appearance on Fall Out Boy's new album. Statement from band front-boy Pete Wentz, and a question from your humble editor, after the jump. Statement: "At some point everyone is gonna find out. So, I guess its time to let the cat is out of the bag. We didn't want to talk about this before we actually heard it because its a once in a lifetime experience. We've announced a couple of guests on the record but "I wish you luck with a capital F" is just one of the thousands of genius ideas thought up by Elvis Costello and he's gonna be singing on Folie a Deux. this isn't a typical appearance as he's alongside the guys in a couple of the decaydance bands on the song. Either way this has been an amazing experience for fall out boy as he is one of our heroes, especially so for patrick. We can't wait for you to have the chance to hear it." Question: Okay, I don't know much about current music. Nothing, actually. But I've been led to understand over the last few years that Fall Out Boy sucks. Is that not true? Have I been misinformed? It was funny when Costello popped up in Talladega Nights, but this? What shit is this? [AbsolutePunk]
