Behind the scenes

 * The episode title is a reference to the nickname Mel Blanc had, "Man of a Thousand Voices," which was also the name of a 2008 documentary about him.
 * With every episode's title card, one of the gang announces the guest star, which is Fred this time.
 * Grey is always on her phone while working, which is what she is known to do in real life.
 * The monsters come from Scooby-Doo, Where Are You!: Redbeard's ghost from "Go Away Ghost Ship," Charlie from "Foul Play in Funland," Captain Cutler's ghost from "A Clue for Scooby-Doo," and the Creeper from "Jeepers, It's the Creeper!"
 * Scooby pulls on Redbeard's beard as he did in "Go Away Ghost Ship."
 * Frank Welker's name has been homaged twice before: In 2003, a villain was called Frank Welker in the DC Comics' Scooby-Doo #74, and then in 2018, Capstone published Scooby-Doo! Encyclopedia, who obviously thought it would be cute to christen the unnamed sheep rustler, from another Scooby-Doo, Where Are You! episode "Who's Afraid of the Big Bad Werewolf," by naming him Frank Welker, perhaps because Welker voiced the character.
