When Lister is being chased by the vindaloo mutation he parodies Bruce Willis' line from "Die Hard 2" (1990); "How can the same smeg happen to the same guy twice?", referencing the previous series when he was attacked by what he thought to be a shami kebab in "Polymorph". "Jaws" is then parodied in the final scene when Lister disposes of the vindaloo mutation by throwing a lager can into its mouth and then shooting at the can, making it explode along with the mutation.
