At the end of the episode when Marshall and Simon are walking through the cemetery, a grim reaper can be seen walking casually in the background.
At approximately 5 minutes into this episode, there is a panning shot past a spider's web and a high pitched voice can be heard saying "Help me...Help me!". This is a reference to The Fly (1958).
When Marshall cautions Devon that his behavior may be dangerous, Devon counters, with a sly grin, "Live fast, die young, and leave a good-looking corpse." One of the most famous sayings in XXth century American culture, it is often thought to have been spoken by James Dean. Actually, it can be traced back to Willard Motley's debut novel, "Knock on any Door" (1947), which was later made into a 1949 film directed by Nicholas Ray, in which the immortal line is spoken by John Derek (as Nick Romano).
The statue seen on Devon Wilde's grave in Eerie Cemetery is a near-exact copy of the "Bimbo inginocchiato orante" ("Kneeling Child in Prayer"), a marble sculpture from about 1830 by Luigi Pampaloni (1791-1847) now in the Galleria d'Arte Moderna in Genova-Nervi, Italy, and copied in many cemeteries worldwide. The Eerie version, however, unlike the original and the cemetery copies, has angel wings, and was probably made specifically for this filming, as a tear springs from its right eye at the end of the story.
The teacher who introduces new student Melanie to the class is named Miss Annabell Lee. Though spelled differently, this is a reference to "Annabel Lee" (1849), Edgar Allan Poe's last complete poem.
