Throughout the series, a lot of references and nods are made to famous and popular TV shows and films. Some notable examples include: The Simpsons, Fawlty Towers, Looney Tunes, Snow White and the Seven Dwarfs and Titanic.
One of the most notable running gags throughout the series, is C-3P0 from Star Wars making a brief appearance in the ship, after which Cassie asks "Who is that guy?"
Also throughout the series, many popular cartoon characters make either cameo or brief appearances, as caricatured versions of themselves, in certain episodes. Some notable examples include: Bugs Bunny, Wile E. Coyote, and Homer Simpson.
Marion, the titular protagonist, is very much reminiscent and a parody of John Wayne's real first name (Marion) and the character he played in the hit 1969 western film True Grit.
