Once per season, someone says the word Beetlejuice (1988). This episode marks the third time it is said (this time, by Annie during the cold open), and an extra in a Beetlejuice costume walks by in the background.
Marks the first time that the piece of music "Daybreak" by Michael Haggins is heard on the show. Abed hums the tune during his story. The song would go on to be heard several more times during the series.
As Britta is describing how each member of the group may be killed, it is shown that she is reading a book called "Warren Piece." This is a play on Tolstoy's famous novel "War and Peace," spelled wrong to show Britta's pretentions to intellectualism.
In Annie's scary story when she teaches vampire Jeff to read, the line he reads successfully is from Shakespeare's King Lear.
The opening credits of the intro are Halloween-themed.
