Trivia: Arseface is based on James Vance, a teenager who made a suicide pact with his friend Ray Belknap, after the two became intoxicated while listening to the band Judas Priest. Vance survived his suicide attempt, but was left with a horribly disfigured face. His parents went on to unsuccessfully sue Judas Priest, blaming the band for their son's suicide attempt.
Trivia: The cast were sworn to secrecy to not reveal the big twist at the end of season one. Reportedly, all the cast members were really good at keeping the secret... except Ted Danson, who couldn't help but give away the twist anytime he tried to explain the show to someone.
