All right, who plays "Hammer" in Hammer & Coop?

Who plays Hammer, aka Jim Turtledove? He looks a lot like Ben Stiller and acts a lot like David Hasselhoff. The true identity of the actor is a bit of a mystery to my co-workers who are obsessing over MINI’s new marketing campaign.
A little help?

Bryan Callen

Confirmation is here.

Super Cool, thanks.
