Will Arnett appeared on “Letterman” last night to talk about his new show “Running Wilde.”

Comic hero Will Arnett appeared on “Letterman” last night to discuss the “Oscar buzz” surrounding his new show, “Running Wilde,” which he created with “Arrested Development”‘s Mitch Hurwitz.

Most of the coverage of last night’s appearance focused on what was ostensibly a clip from the show, featuring a “cameo” with Paul Shaffer. Sure, the clip also features the show’s costar Keri Russell—but am I the only one who doesn’t think this is actually a clip from “Running Wilde”?

The clip mostly features Shaffer swearing like a sailor and proclaiming, “You know what there’s no such thing as? An easy ten grand. They took that away when they took away ‘Hollywood Squares.’”

I think it’s possible that Arnett set this up as a dummy clip with his new digital content creation company DumbDumb, which has been cranking out some awesome videos for corporate clients like Eclipse gum.

Either way, Arnett can do no wrong in our book. The clip is funny, and “Running Wilde” is likely to be awesome. Whether it’s possible to be as awesome as “Arrested Development” is dubious, but if anyone can pull it off it’s Arnett.
