The fourth graders are rehearsing for the "Thanksgiving Extravaganza", where they have to perform "The Miracle Worker", which is the story of Helen Keller, starring Timmy as Helen. Butters provides them reports that the kindergarteners' play is the greatest show he has ever seen, and the other kids agree to put extra effort into making their play better. Cartman agrees to adapt the play into a musical, and eventually Jeffrey Maynard, who played the lead in "Les Misérables" for the Denver Community Playhouse (which is why he is singing his lines), is brought in to help. The kids also decide to replace Helen's pet dog with a turkey, which is also to perform tricks for the audience. Timmy helps to pick out the turkey, and chooses a disabled turkey which he names "Gobbles".
