WATCH: Superfan Paul Rudd dresses up like Santa, joins the Chiefs band

Maybe Paul Rudd's line from "Anchorman" should've been "Whammy!"

The comedian and rabid Kansas City Chiefs fan went to town on a drum before the team's game at Arrowhead Stadium on Sunday. He looks like he belongs right in the "TD Pack Band."

Via Kansas City Chiefs:

Rudd hails from nearby Overland Park, Kan. He's a Shawnee Mission High and K.U. graduate; if the team had a celebrity spokesman, he'd be it.

There's no way he'd miss a potential playoff-clinching game like this one. And of course, he's wearing a full-on Chiefs Santa suit.
