Trivia: At the end of the episode Shawn and Gus show up at Jules' crime scene and she tells them they already have a detective who is in the kitchen alphabetizing, likely a nod to USA Network's OCD Detective Adrian Monk from the show "Monk" which was set in San Fransisco.
Trivia: Ralph Macchio features as a prosecuting attorney. At one point, Gus speaks a quote from "My Cousin Vinny", and the other attorney calls it "a terrific film." Macchio objects, saying "it's OK... Decent at best." Macchio featured in that movie.
Trivia: Alan Ruck, who plays the bank robber, is (arguably) best known for his role in Ferris Bueller's Day Off, where his character's name is Cameron. In this episode, Ruck plays a bank robber who takes hostages, including Gus. The SWAT commander that attends the bank robbery (a character who hasn't existed before) is named Cameron. Possibly a deliberate choice given Psych's frequent pop culture references.ADDITIONAL: Series 8, Episode 3 - Ruck co-stars as a news weatherman; when Shawn introduces himself, he says .".and this is Gus, my black Cameron" - a much more clear reference to the Ferris Bueller character.
