 Every year for Thanksgiving, the fourth grade puts on a production of The Miracle Worker. This year, however, they face stiff competition from the kindergarteners, who are putting on a highly professional show with pyrotechnics and musical numbers. Desperate not to be shown up, Cartman decides to turn the show into a massive musical production finishing with a stunt turkey leaping through a ring of fire. Unfortunately, Timmy (who is playing Helen Keller), has adopted a hopelessly untalented turkey as his pet and refuses to let it be replaced.
