This episode marks the return of Golden Locks and Hair Razor, both of whom were mentioned in "Super Mayhem", with Cleft saying that Hair Razor was rewritten as a seperate character instead of being Golden Locks' evil alter-ego.
It's revealed that Golden Locks' real identity is Katherine Marrow, or just Kathie, and that she used to be a science teacher.
Homestar Runner - The opening scene of the episode where a mailman sticks a comic book in the Turner's mailbox and Timmy gets the comic from the mailbox saying "It's here! It's here! It's finally here!" is similar to the Homestar Runner short "Compy Catalog". Although, Strong Bad says the aformentioned line before getting the contents from his mailbox.
Stripperella - Budget Thief, one of the supervillains in the Golden Locks comics, is similar to Cheapo, a villain from Stan Lee's TV series Stripperella whose main gimmick is committing crimes on a budget, like stealing replicas of expensive things, or stealing copper coins.
