In-joke reference: In the same scene with the mug with the quote "Don't mess with the bull", Paul Gleason's character, Sheriff Halderman, receives a printout of an e-mail from one of his deputies. He looks at it and says "What's this? What, did you find D.B. Cooper?" Paul Gleason played Remson in the 1981 movie "The Pursuit of D.B. Cooper".
A scene late in the film that takes place inside a defunct airplane, sports a reproduction poster for Charles Chaplin's City Lights (1931) inexplicably hanging inside.
