Patty is a girl in
Greg’s grade. She is something of a teacher’s pet, and Greg develops a vendetta against her when she stops him from cheating on a geography test. She has dreams of becoming an actress and is cast as the lead role of Dorothy in the school’s production of
The Wizard of Oz. However, her chance at stardom is ruined when Greg pelts her with apples on stage, breaking her glasses and cutting the entire play short.
