Louise, Cheese's creator, returns to Foster's for the second time, in this episode since "Mac Daddy".

When Frankie threw the phone out in the begining, she has it again.

When Eduardo is loopy from the influence of the anesthesia, his mannerisms and some of his dialogue mimics Cheech Marin's character (sometimes known as Pedro de Pacas) from the "Cheech and Chong" films of the 1970s.

Frankie's Packages: At the beginning of the episode, Frankie is seen carrying four packages to be delivered, a green package, a blue package, a red package, and a purple package. Purple Package: In the next invaded episode ("Ed, Edd, n Eddy"'s, "The Eds Are Coming! The Eds are Coming!" ), Sarah looks under Jimmy's bed finding the purple package "Belly Bomb Bon-Bons" which is empty from Jimmy eating them all. Red Package: In the "My Gym Partner's a Monkey's" episode "That Darn Playtpus", Inside Adam's locker while seeing the platypus eating cheese is the red package.

Blue Package: Lastly, in the Grim" Adventures of Billy and Mandy's" "Billy and Mandy Moon The Moon", Billy's Toy is seen with the blue package.

Cheese says "Noooo!" once, but other than that, the only thing Cheese says is "Gotta Go!"

This is the second episode not to be centered at the house, however in the credits, Frankie is in Madame Foster's car outside the house. "Infernal Slumber" was the first not to be centered at the home. Additionally, Mr. Herriman does not appear in this story.

Fourth time we see Eduardo naked.

This is the fourth time Wilt has gone to jail, the second trip to the cooler for Mac, Blooregard and Coco and the first time for Eduardo, Madame Foster and Jackie Khones.

Look Closely: Wilt is on the cover of the World Weekly News waving a United Kingdom flag, acting as a werewolf from "One False Movie".

Eduardo was under the influence of anesthesia (he had a tooth removed), and it made Bloo think he had had his brain removed.
