Psych celebrates a big milestone when it airs its 100th episode, called "100 Clues," on Wednesday, March 27. Check out our special preview of the episode and find out how you can be involved in helping Shawn and Gus discover who done it. 

As the name suggest, Psych's 100th episode is a tribute to the 1985 classic movie, Clue, and features guest stars from the original film, including Martin Mull, Christopher Lloyd, Lesley Ann Warren, Garrett Morris and special guest stars Curt Smith and Steve Valentine. 

BuddyTV got a sneak peek at the episode and here are some things you need to know.

Fans will get to vote on the ending. As the episode plot thickens, fans on both coasts will work along with Shawn and the gang to identify the true murderer, determining the landmark episode's outcome by casting their votes on psych.usanetwork.com and Twitter. The hashtag to vote on Twitter is #WhoDDit

The episode is chock full of Clue references. If you've seen the movie Clue then you'll probably have as much fun as I did counting all of the various ways that they referenced the film throughout the episode. I lost count after noting no less than 17 separate Clue references. Of course i would be too spoilery to reveal them all, but I will tell you that at least three lines from the film are used in the episode, plus countless other moments I guarantee every Clue fan will notice. 

The episode is also chock full of plenty of Psych references. But don't worry if you've never seen Clue that you won't understand what's happening in the episode. Underneath all of the Clue references, there is still Shawn and Gus doing what they do best: getting themselves into trouble. There are tons of references to the show itself and there is even a very cool flashback that harkens back to one of Shawn and Gus' first cases. From the famous "Suck iiiiit" to the guys' celebration dance, there is a lot in the episode that will make any Psych fan smile. 

There is a fair bit of singing in the episode. I don't know if all the recent talk of a musical episode had me more in tune to any reference to music or singing, but there sure seemed to be a lot of that going on in this one. There are more than a few instances where one or more of the characters breaks into song. You'll definitely hear Shawn and Gus belt out a few notes here and there and all I can say after hearing even those brief moments is: bring on the musical!

It will make fans laugh harder than they have in a while. I am not kidding when I saw that by the time I had reached the halfway point in this episode, I had laughed more than I had probably in the last two episodes put together. Considering how funny this season of Psych has been, that's really saying something. Maybe not everyone will have the same reaction I did, but I will be surprised if most Psych fans don't find "100 Clues" absolutely hysterical -- whether they've seen Clue or not. 

What do you now that you've gotten some tidbits about the Psych 100th episode? Has this made you more excited than ever to see "100 Clues"? Don't forget to cast your vote when the episode airs and help decide who the killer will be!

Psych airs on Wednesday nights at 10pm on USA.
