Philip Glass appears in the background in the Season One episode, "Mr. Hankey, the Christmas Poo" as the minimalist composer from New York who performs music during the "happy, non-offensive, non-denominational Christmas Play".
Phillip Glass wears a black shirt, black pants, and has curly black hair. He can be seen in front of two gray keyboards.
- Matt Stone and Trey Parker strongly dislike Glass, citing him taking the character and the magic out of Christmas. They they mention that can "you basically give a third grader a keyboard, tell him to mess around, sell that music as one of Phillip Glass' albums, and no one would know the difference."
