Cast Incest: Gail has a relationship with Gordon during the time the group moves to Malibu. Mary Steenburgen (Gail) played the mother of Will Ferrell (Gordon) in Stepbrothers. Furthermore, she plays his step-mother (the wife of his biological father) in Elf.
The Cast Showoff: Mary Steenburgen really plays the accordion. Which is why Gail is frequently seen playing it.
The Danza: Mel Rodriguez plays Todd Rodriguez (last name mentioned by Phil in "The Big Day").
Dyeing for Your Art: Will Forte really did shave half of his head for a season. Mel Rodriguez also followed suit, though for a shorter time.
Enforced Method Acting: Kristen Schaal ate about 50 real crickets on set because nobody told her they also had fake ones made of candy.
Executive Meddling: Averted, surprisingly. According to Kristen Schaal the only demand the higher-ups at FOX made was that there be no visible bodies shown. Other than that, the team has full creative freedom.
