In case you missed it, Will Ferrell was at the Green Bay Packers game last night.

He was sporting Packers colors and led the crowd in a rendition of Roll Out the Barrel.

Pure awesome.

What we’re trying to figure out is why Will Ferrell was at the Packers game last night. Ferrell is from Irvine, California. We know he’s a football fan — a big USC fan, in fact. He’s often on the sidelines at SC games.

Last night is the first evidence we have that he might be a Packers fan, though.

Another possibility is he was at the game for something involving the next Anchorman movie. As you can see from the photos, he’s got the sweet Ron Burgundy mustache working.

“Hey everybody, come see how good I look!”
