  • Fred announces the guest star in the title card.
  • A painting of the Indian Witch Doctor from the Scooby-Doo, Where Are You! episode Decoy for a Dognapper shows up in the background of a hallway shot.
  • Daphne mentioning she speaks mime, recalls the Be Cool, Scooby-Doo! episode There Wolf.
  • Based on their position sitting on the mattress as it was catapulted out of the casino, the last person out was Tess Flemmings, with Penn just before her. The Madds Markson Monster was actually one of the first out as it was near the front of the mattress.
  • Cartoon Network was supposed to air this episode on August 19, 2019, but pulled it in favor of an episode of Teen Titans Go!
  • This is the first episode where the guest star is actually the villain.
  • A sneak peek of a scene in pencil was released on Vimeo.

Cultural references

  • The escape from the hotel's demolition in progress is reminiscent of a scene in the film Die Hard, when McClane jumps from an exploding building.
  • The trick Teller pulled off with cardboard cutouts on a model train set is exactly what Kevin McCallister pulled off in the film Home Alone, as part of a fake Christmas party setup to ward off burglars Harry and Marv.


Animation mistakes and/or technical glitches

  • None known.

Inconsistencies/continuity errors and/or goofs/oddities

  • If the hotel / casino is being demolished in a few hours, why is it still full of slot machines, at least one of which contained money?
  • Fred is wrong when he says Teller was last out of the casino. The Madds Markson Monster can be seen as one of the first out the window.

Penn: Seen it a million times.

Daphne: (translating Teller) Don't worry. I speak mime. He's saying that he was being chased by that horrible monster and hid in this cupboard.

Fred: Now let's see who the ghost of Professor Madds Markson really is!
All: It's, it's. Huh?
Velma: Yeah. I don't know who this is.
Tess Flemmings: My name is Tess, Tess Flemmings.
All: Tess Flemmings?
Tess Flemmings: (Penn helps her out of the trap) Thanks, Mr. Jillette.
Scooby: Tess who?
Tess Flemmings: I'm a Las Vegas history buff. I sneaked into the hotel to get some last footage of the place before it's controlled demolition. And thanks to you meddling kids and magic legends Penn & Teller I got some great footage.

Daphne: Really impressive Mr Teller. But why? Why did you do it?
Teller: Because I wanted to pull off a magic trick big enough to impress Penn.
Scooby: Huh? Did you know he could talk?
