Although Arthur is directed primarily toward a prepubescent audience, over the years it has gained a substantial cult following among older viewers. The show regularly incorporates satirical parodies of adult-oriented topics and references to pop culture, including parodies of South Park, The Sopranos, Beavis and Butt-head, Dr. Katz, Professional Therapist, The Jerry Springer Show, Oprah and Law & Order. Many of the references and topics covered are ones with which the target audience most likely would not be familiar. In the episode Desert Island Dish, Francine holds up a cage containing a swallow and then shows a coconut, saying the bird was carrying the coconut. This is a subtle reference to Monty Python and the Holy Grail and would only be picked up by older audiences.
