Plot Hole: It is never explained how Lassiter and Jules knew where to be, and at what time they were needed in apprehending the suspect at the victim's house.
Nitpick: When they are shown the matchbox with the club's name on it, Shawn wonders how Herb got into "The Dollhouse" when they themselves are never able to. In the next frame, you see Shawn and Gus walking into the club without any problems. Since they don't have police credentials, how did they get in?
Pineapple Spotting: 1. The pineapple was to the left of the picture of the dead inmate and his mother taken in front of the church. 2. There is also a pineapple on the tote bag of a woman who walks past Shawn and Gus on the boat after Gus gets seasick.
Pineapple Spotting: A lampshade in Declan's house is made up as a pineapple skin.
Goof: When Strabinsky is having flashbacks about the operation in Bolivia, we see a plaque that reads "Embajada de Bolivia." An embassy is supposed to represent a country outside of its territory. Therefore, there is no need for an embassy of Bolivia in Bolivia.
"Wild Horses" by The Sundays
Pineapple Spotting: A glass pineapple sitting on the hotel room bar seen as Despereaux makes his cocktail.
Psych-out: There are back and forth switches between Dulé (Gus) making up passwords and Cary Elwes (Despereaux) making exclamations about how he was set up.
All of the older stars working with the main cast on this episode were in Twin Peaks.
The first time the Cinnamon Festival is mentioned is in the Pilot episode. Shawn tells Gus that he doubts that he could beat him up because of how their last scuffle turned out. Gus says that it was at the Cinnamon Festival and that he was six and had a cast.
In this episode, Shawn and Gus are invited to a Cinnamon Festival in the town of Dual Spires.
Trivia: Shawn introduces Gus as Lodge Blackman, referencing the Black Lodge (a strange extradimensional space) from the show Twin Peaks.
The name of the murder victim, Paula Merral, is an anagram for "Laura Palmer," the murder victim in Twin Peaks.
The opening shot of the Stay 'n Save Motor Inn is actually Accent Inn Vancouver Airport Hotel which is located in the suburb of Richmond, near the Vancouver International Airport. The Inn's street address is 10551 St. Edwards Drive.
The still shots of the entrance to the Santa Barbara Police Academy is actually the entrance to the Los Angeles Police Academy in Chavez Ravine, just north of downtown Los Angeles.
Built around the pistol range made for the 1932 Olympics in Los Angeles, the "old" academy is still in use today for recruits in the latter phases of their training, as well as in-service training for more seasoned members of the department.
Pineapple Spotting: There are pineapples painted on a teapot jar in the restaurant. The jar also has a pineapple lid.
Nitpick: When Henry Spencer escorts Allison to Shawn's bedroom, she admires Shawn's hand turkeys. Henry says that Shawn was never a good artist. However, in "Sixty Five Million years off" Shawn is shown as a fairly good artist when he draws a T-Rex at the crime scene in under a minute.
Pineapple Spotting: There is one in the grocery bag in Yang's car at the beginning, and there is another small pineapple in Henry's kitchen beside his salt and pepper shakers.
Trivia: Because the actor that played young Shawn in Mr. Yin Presents is different than the one this year, the picture that Yin touched at the end of Mr. Yin Presents is not the same as the one that Allison shows Shawn in the beginning of this episode. Yang looks exactly the same, as does the background, but the boys are clearly different.
When Shawn fakes a British accent, he cites "Phineas and Ferb's grandpa" as a reference. This character is played by the episode's guest star Malcolm McDowell.
