Eric Cartman
In 2007, Szubanski ventured into musical comedy, taking on the role of William Barfee in the Melbourne Theatre Company production of the hit Broadway musical "The 25th Annual Putnam County Spelling Bee". "Variety" described her performance as "sensationally good". "Australian Stage" said, "Magda Szubanski as the Eric Cartman-esque William Barfee steals the show."
