At the beginning of the film, when Birdee and Bernice are leaving Chicago to stay with her mother in Texas, the two are driving on a freeway. They pass a bus with a billboard on the side advertising for the television show Birdie was just dumped on. The billboard reads: "Toni: She'll change your life!"
When Bernice walks into the classroom, the teacher is going over grammar sentences and correcting them. When Bernice walks back to the back of the classroom, the girl sitting next to her is holding a science book.
When Birdie goes to the school to drop off Bernice's lunch, Chris (the school employee) alternates between facing Birdie and facing Bernice between shots.
