The "World's Biggest Tiny Toon Fan" in the sketch, Night of the Living Dull, is based on Dennis "Quozl" Falk, an actual overly-obsessed fan the production team encountered while working on Tiny Toon Adventures. He was a stalker who sent Tress MacNeille disturbing letters which caused her to fear for life and cancel any convention appearances she was planning to make around where he lives.
Parodies include 'The Nightmare Before Christmas,' 'Night Gallery,' "The Tell Tale Heart" by Edgar Allan Poe, 'Casper the Friendly Ghost,' 'Ghostbusters,' 'The Hound of the Baskervilles,' 'The Devil and Daniel Webster,' the Abbott and Costello monster movies, 'Night of the Living Dead,' 'Frankenstein' and the "Nightmare at 30,000 Feet" episode of 'The Twilight Zone.'
The Brain from 'Animaniacs/Pinky and the Brain' makes a cameo in the 'Frankenstein' parody. Elmira says "I'll play with you later!" This turned out to be a prophetic statement as the two would go on to star in the short-lived 'Pinky, Elmira and the Brain.'
The final appearance of the Tiny Toon gang on TV, although Elmyra later appeared in a short-lived spin-off, Pinky, Elmyra & the Brain (1998) and the gang has made some appearances in comic books and video games.
