Wahlburgers Wahlburgers

Mark Wahlberg gave a knockout performance as boxer Micky Ward in the 2010 Oscar-winning film The Fighter. On Wednesday's season finale of Wahlburgers (10:30/9:30c, A&E), the movie star is returning to the ring — but for a very different cause.

In this exclusive sneak peek, Mark decides to punk his longtime friend Henry "Nacho" Laun by having him unknowingly go up against professional boxer Mike Lee. "Nacho wants to eat my burgers? He's gonna eat that leather," Mark tells mutual friend Johnny "Drama" Alves. But is Johnny right to assume that Nacho's "ass is in trouble?"
