First episode to feature what will become one of Shawn's catchphrases: "Wait for it..... wait for iiiiiiiiiiiit..."
(at around 21 mins) Pineapple sighting: a pineapple upside down cake from an Easy-Bake Oven.
When Special Agent Lars Ewing (Lou Diamond Phillips) introduces himself as an FTD agent, Shawn makes a reference to Florists' Transworld Delivery. This joke is added to by Agent Ewing's tattoo, which is Kanji for "flower branch".
Lou Diamond Phillips plays an FTD Agent. In Speak Now or Forever Hold Your Piece (2006) (from season 1), when Shawn is calming down Lacey, he tells her to think of Lou Diamond Philips.
