When Tarantella is filming Courage next to the quicksand, the TV is showing the scene live with another TV in the top right corner of the live scene, but when Tarantella is being sucked into the quicksand, the live scene no longer shows the TV in the top right, despite the camera being in the same spot as before.
On the quicksand box Courage finds in the attic, it says "For Ages 3 and Up" in the top right corner.
The blue loveseat in the living room is missing.
The fishonnary wanted water from Muriel. Why didn't she just wear that water helmet she was later shown wearing in the episode?
Mr. Nasty: Stupid, ugly, worthless losers!
Eustace: (watching himself on the TV) Hey, this is pretty good!
Benton Tarentella: I want you to make that waitress cry.
Muriel: But that would be so mean.
Benton Tarentella: Yes.
Muriel: (to waitress) Oh, hey...uh, your toast is soggy.
(giggles--to Courage) I feel so naughty.
Mr. Nasty: Hi there, or in your native language: ohh ohh ohh ee ee ee ahh ahh ooh.
Mr. Nasty: (To Eustace) You can't grow hair, you can't grow plants, the only thing you can grow is stupider!
Eustace: I hate Scotland.
Eustace: Where's my peanuts?
Eustace: (Sprays mustard and ketchup on Courage) Hey, look! Stupid dog's now a stupid hot dog!
Muriel: Don't worry, Courage. It's all just acting... I think.
