Even though he's now an A-list movie star, Rogen got his start on TV in Judd Apatow's 'Freaks and Geeks' and 'Undeclared.' He'll head back to the small screen for a guest spot on the season premiere of FX's fantasy football comedy as Dirty Randy, a friend of Rafi's whose wild antics have become the stuff of legend.

'The League' Season 3 premieres Thurs., Oct. 6, 10:30PM ET on FX
