Betty laughed just like Schnozmo at the end of the episode.
Betty and Veronica - This episode is a reference of an ongoing comic book of the same name, except that Betty is the black haired one, and Veronica is the blond one.
SpongeBob SquarePants - At one point, in response to Veronica's question, Katty answers "Meow, no.", to which Veronica replied "Oh, what do you know? You're a cat.", similar to the moment in the SpongeBob SquarePants episode "The Secret Box", where Gary does the same in response to SpongeBob's question.
