Kent Brockman notes that Mr. Burns stole Christmas from 1981 to 1985.
Lisa running around telling everyone what Lisa's Slurry is made of.
In "Where's The Cheat?", when asked if he had seen The Cheat, Bubs looks over his inventory, which has no Cheats but does have both ketchup and catsup. This is a reference to Mr. Burns being confused about whether to buy either such condiment when at the store
The scene where Lisa tries to stop the townspeople recycling before jumping on a truck and seeing barrels of Lisa slurry parodies a scene in this film with pod people in place of recyclers and pods in place of the slurry.
The scene where Burns chases Lisa asking her to help him parodies the opening sequence to this show.
