* ActorAllusion:
** One episode featured Creator/BobHope as an angel who had a problem when the heavenly computer was being upgraded. When the work on it was completed at the end of the episode he said --altogether now -- "Thanks for the memory."
** In the episode titled "I Was a Middle-Aged Werewolf", Jonathan appears as a wolfman to help a little boy get over his fears. One of Creator/MichaelLandon's earliest roles was the titular lycanthrope in ''Film/IWasATeenageWerewolf''.
* DirectedByCastMember: The only regular cast members were Michael Landon and Victor French, who between them directed all but five episodes of the entire run (French did 12, Landon 94).
* GeniusBonus: The blessing that Arthur gives to Mark and Jonathan is an old Celtic blessing. Perfect for someone who (thinks he is) King Arthur.
* WrittenByCastMember: Michael Landon penned numerous episodes, including the pilot and the SeriesFinale.
* YouLookFamiliar: in one episode, [[Series/{{Bonanza}} Pa Cartwright]] is an old actor who swears he saw God in the audience of his play.
** Much LampshadeHanging is done in "I Was A Middle-Aged Werewolf" regarding how much the actor in ''Film/IWasATeenageWerewolf'' looks like Jonathan. Jonathan, naturally, is skeptical of this.
