James Roday - Roday is not actually his last name. He was born James David Rodriguez. He had to change his name as there was already a James Rodriguez in the Screen Actors Guild, so he chose the name Roday from a character in ‘The Three Sisters,’ the play he was in at the time.

Dulé Hill - Hill’s talent for tap has been featured in several different episodes of 'Psych.' He’s trained in ballet, and performed in ‘The Tap Dance Kid.’

'The West Wing' - Many may recognize Dulé Hill from his role as Charlie Young on ‘The West Wing.’ He went from a side character to a primary role, however by season 7 he chose to only come back for a few episodes. That was in part due to the filming of a new show. Three guesses which...

Pineapples - As many who follow the show know, they add a distinct pineapple flair to every episode. However, did you know that it was actually created spontaneously? In the first episode, James Roday referenced a pineapple prop in the kitchen, and the team liked it so much that they kept it. Now there are entire websites devoted to finding the cleverly hidden pineapple in every episode.

'The Breakfast Club' - Four out of five of the stars from ‘The Breakfast Club’ have appeared on the show. Molly Ringwald played Nurse McElroy in season six, while Judd Nelson played Dr. Steven Reidman. Anthony Michael Hall had a recurring role in seasons seven and eight as Chief Harris Trout. The star of the four was Ally Sheedy, who played the psychotic yet intriguing character, Mr. Yang. Did you recognize her?

Animated - Childhood flashbacks have been a part of every season, but at the beginning of the series, there were also animated shorts. They played in the commercial breaks, and were about some of the character's adventures as kids.

'Monk' crossover - In order to attract viewers to the new show, USA Network would do crossover commercials, many of which involved 'Monk.' They were just little blips to suggest that those who watched ‘Monk’ may also like ‘Psych.’ Though there were hints towards them meeting in the season finale...

'The Cosby Show' - Shawn frequently makes the joke that Gus played Bud on ‘The Cosby Show.’ While this drives Gus nuts, he does have a point. Gus’ mom is played by Phylicia Rashad, and Keshia Knight Pulliam (who played Rudy) makes a guest appearance as his wife. The point is driven home when Deon Richmond, who actually played Bud, calls him Bud in the season finale. Talk about an identity crisis.

'American Duos' - Though it is an incredibly memorable episode, the ‘American Idol’ parody was not in the original plans. Roday and Hill were goofing around on set after work with Tears for Fears and Michael Jackson mash-ups, and director Steve Franks loved their impressions. Just imagine this face next to Roland Orzabl.

Cameos - We have mentioned a few already, but here are the main celebrity cameos throughout the ‘Psych’ seasons!

Tim Curry - Appearing in the ‘American Duos’ episode, Curry plays the judge Nigel St. Nigel.

Cary Elwes - An often-seen character and Shawn’s rival, Elwes plays the amazing thief, Pierre Despereaux.

Curt Smith - Playing himself, it’s not surprising that Curt Smith finally shows up in the series. Considering all the Tears for Fears references, we’re surprised it wasn’t sooner!

Danny Glover - Danny Glover plays the coach of a baseball team for one episode in season six. Wade Boggs also appears in this episode.

Jane Lynch - Jane Lynch plays the cocky Coast Guard Commander.

Staff cameos - Even the staff got in on the fun! Several writers and directors starred in ‘Psych’ episodes. Some even played more than one character. Creator Steve Franks has actually been in several episodes.

'Big Daddy' - You may know that Steve Franks is the creator of the series. He was also the creator of the film ‘Big Daddy’ from 1999. The film starred Adam Sandler, as well as Dylan and Cole Sprouse.

A rocky start - Most major networks liked the pitch for ‘Psych,’ but didn’t want to actually sign it on. USA Network was the only one that was interested. This makes sense, since their slogan at the time was “characters welcome.”

MC Clap Yo Handz - This is just one nickname out of many that Shawn gave to Gus on the show. This bit is featured in numerous episodes, and can be anything from "Jazz Hands" to "Hummingbird Saltalamacchia." The writers don’t get the credit for this running gag. James Roday actually started it by calling Dulé Hill, “Gus Silly-Pants Jackson” during early filming.

The theme song - The oddly perfect theme song for the show is by The Friendly Indians. The interesting part? Both Steve Franks (pictured) and Tim Meltreger (another writer) are in the band. Now the lyrics all make sense.

Bloopers - ‘Psych’ has had a lot of bloopers. A lot. Instead of just putting them in the DVD specials, they were included at the end of the program. There are over two and a half hours worth of material.

Kurt Fuller - Kurt Fuller appeared in a number of films and series before gaining the recurring role of Woody in ‘Psych.’ He was in shows including ‘Seinfeld’ and ‘Xena: Warrior Princess,’ as well as movies like ‘Wayne’s World’ and ‘Midnight in Paris.’

Timothy Omundson - Before this recurring role, Omundson was also in plenty of series. So many in fact, that he starred in the documentary ‘The Guy… Who Was In That Thing.’

Episode remake - Remakes are popping up everywhere, but ‘Psych’ was actually the first show to remake its own episode. In season eight, they remade their first ever episode.

"I can fix that" - During an episode in season 7, Dulé Hill uses the phrase “I can fix that” throughout the episode. This is a throwback to his role of Sam in the movie ‘Holes.’

'Dual Spires' - An episode takes place in the tiny town of ‘Dual Spires.’ This is based on David Lynch's series ‘Twin Peaks,’ to which 'Psych' makes numerous references.

Carlton Lassiter - Carlton’s name is not random. It’s actually a conglomeration of two different characters: Carlton Banks, from ‘The Fresh Prince of Bel-Air,’ and Paul Lassiter from ‘Spin City.’

"C'mon son!" - Yet another quote that was not originally written in to the series. Dulé Hill was watching Ed Lover on set, and decided to incorporate one of his tag lines into his character.
