Scary Sherry: Bianca's Toast - S1-E15
Trivia: In this episode, Chelan Simmons (Bianca), dies by getting electrocuted. In Final Destination 3, her other film, she also dies by getting electrocuted.
Trivia: There is a scene where Shawn, Gus, and Vivian are sliding in an open hallway trying to hide from the orderly who is taking Bernie on the elevator to his lobotomy at the mental facility. The scene is a total re enactment of The Breakfast Club movie scene where Molly Ringwald, Judd Nelson, Emilio Estevez, Ally Sheedy, and Anthony Michael Hall are sliding in an open hallway trying to hide from Dean Paul Gleason when they broke out of detention. Molly Ringwald guest stars in this episode too. (00:34:15)
Earth, Wind and... Wait for It - S3-E12
Trivia: The fire inspector tells the investigators to fill out form IG-88. IG-88 was a robot bounty hunter from 'The Empire Strikes Back.'.
Trivia: When Danny Glover tells James Roday "I'm too old for this crap", it is a slightly cleaner version of the catchphrase he uses in the Lethal Weapon movie series. In the movie he says "this shit". (00:25:20)
The Polarizing Express - S5-E14
Trivia: When Skylar Gisondo is talking to Tony Cox and James Roday about "how we changed, sometimes from week to week" it is a sly reference to the child actor change in season 5 from Liam James to Skylar Gisondo. (00:21:05)
Lights, Camera... Homicidio - S2-E13
Trivia: The TV studio in this episode is the actual studio where Psych is filmed.
Cloudy...Chance of Murder - S1-E12
Trivia: This episode was remade in the final season, titled "Remake, aka Cloudy...with a chance of improvement". The cast and crew considered it to be the weakest episode made in the series, and wanted to improve on it.
Remake A.K.A. Cloudy... With a Chance of Improvement - S8-E3
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. (00:33:05)
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.
Trivia: When Shawn and Gus ask Henry about previous residents of Lassie's condo who've died mysteriously, the first person Henry mentions is named Ray Brauer, which was the name of the dead kid in "Stand By Me."
Trivia: There is some sort of reference to a pineapple in almost every episode of the show.
Trivia: Bernie Bethel reprises his role as a mental patient in this episode. It is reminiscent of his role as a mental patient in One Flew over the Cuckoo's Nest where he played Billy Bibbit.
Chosen answer: "Psych: The Musical" was supposed to air during the regular season 7 schedule, before Chief Vick is suspended and Jules discovers Shawn's lie, but the network decided to push it back to air as a special episode, sort of as a tie in with the holiday season and a lead in to season 8, which was to begin only a couple of months later.
