Trivia: While filming an episode of 3rd Rock from the Sun, a guest actor playing a carnival strongman told John Lithgow that, growing up in a small town, his father was similar to Reverend Moore.

Trivia: With the Principal's knowledge, 24-year-old Kevin Bacon attended the Provo Utah High School as "Ren McCormack", a transfer student from Philadelphia to get into his role.
