When Fry attempts to call for help, Hermes asks "Who you going to call?" Fry gets cut off at "Gho-" when the operator says "The number you have dialed has been lame since 1989" - the year Ghostbusters II (1989) was released.
The Robot Devil is seen reading a magazine entitled "Life in Hell", a reference to both "Life" magazine, and series creator Matt Groening's original comic strip "Life in Hell."
Robot Devil mentions that he and Fry once traded hands, which is a reference to Season 5's The Devil's Hands Are Idle Playthings (2003).
The butter substitute visible when Bender haunts Fry via his toast is called "It Sure Ain't Butter!"
The heart attack Bender causes Fry to suffer is his fourth; he previously mentioned in Fry and the Slurm Factory (1999) that he suffered three when he was in high school.
