Full credits

The following credits are how they are seen on-screen (or as close as possible).


  • The episode is a pun on how one can cook meat, usually steak.
  • In real-life, Phyllis Diller was actually only married twice, to Sherwood Diller (m. 1939–1965) and Warde Donovan (m. 1965–1975). At the time she appeared in this episode, she was married to her second husband.
  • All but one of Diller's fictional husbands are named and seen.
  • Diller passed away on August 20, 2012.

Animation mistakes and/or technical glitches

  • Shaggy's shirt is colored grey and his neck as Daphne's hair when the Mystery Machine drives to the Magic Mansion.
  • Shaggy and Scooby try to squeeze in the Mystery Machine from its closed door when the shot is from the inside.
    • Also, when Shaggy gets scared by the giant spider on the wheel, his head goes through the car roof.

Inconsistencies/continuity errors and/or goofs/oddities

  • It was never revealed who the gargoyle was.
  • How did Alberto and his accomplice change into their costumes so quickly to prevent the gang from rushing back to the mansion? Everyone immediately took off after the seance.
  • Fred and Daphne want to take a fake detour knowing that it will likely lead to a wrong turn. Fred even acts surprised when it's revealed what he already knew would happen.
  • The gang's positions in the laundry baskets change after the phantoms pass by. For example, despite Shaggy and Scooby landing in the same basket, Shaggy is in with Daphne when the gang go to leave. Not to mention that the positions of Fred, Daphne and Velma differ to when they first got in the baskets.
  • Lucas disappeared to check on his wife, which would mean he would have to go back to the Magic Mansion, but he says about checking on her "here," as in Diller's own mansion, making him look complicit in his wife's spying (or he was trying to prevent it).
  • Casey Kasem's first name is credited "Casy" in the end credits.
