Stranger Than Fiction's signature piece is Phenyx. Their band Phenyx (comprised of the cast's alter-egos), reunites each performance to sing a collection of their old songs in a Behind the Music informercial-like setting. The twist, of course, is that the songs are made up on the spot from fictional titles provided by the audience prior to the show. Guests of this special performance are invited and encouraged to challenge the band with the silliest of titles!
