Nigel St. Nigel, played by Tim Curry, is the first to coin the nickname "Blueberry" for Gus's Toyota Echo. Which later Shawn uses as his own name for the car.
Shawn mimics Tim Curry's pronunciation of the word "no" to his face in this episode, in a possible reference to Curry's performance in "Clue" (1985). He, Shawn, continues to use the pronunciation throughout the series. The eventual 100th episode of the series is a tribute episode to "Clue."
