Season four … it’s amost here! To help wile away these last few days ’til Shawn, Gus, Lassie and the gang hit our screens again (August 7, 10PM ET, USA), 10 reasons to be fist-bumping Psych-ed about the season ahead:

1. The Guest Stars!
The season’s guest stars include Cary Elwes, Rachel Leigh Cook, James Brolin, Sendhil Ramamurthy, Robert Patrick, David Naughton, Tom Wilson (Biff from Back to the Future) and Christine Baranski

2. The Bobbleheads!
Shawn and Gus bobblehead dolls: They talk. And they bump fists.

3. The Storylines!
Among season four’s storylines: a western-themed episode (with Brolin), a Bollywood-themed episode (with Ramamurthy), an exorcism, the attempted murder of Lassiter (Timothy Omundson), more jabs at The Mentalist and the continuation of Shawn’s relationship with girlfriend Abigail (Cook) – sorry Shawn (James Roday) and Juliet (Maggie Lawson) fans

4. The Season Premiere!
“Extradition: British Columbia” finds Shawn and Gus (Dule Hill) trying to capture Despereux, a wily international art thief (guest star Elwes)

5. The Books!
Psych textbooks: meh. Psych novels: fun! Check out Psych: Mind Over Magic and Psych: A Mind Is a Terrible Thing to Read

6. The Nicknames!
Lavender Gooms … the nickname by which all other nicknames should be measured. Of course, it’s just one of many faux monikers Shawn has slapped on Gus throughout the seasons, as this YouTube clip illustrates.

7. The Comic Con Panel!
Watch the cast and producers’ Comic Con 2009 panel, which includes lots of cast and character tidbits, Dule Hill showing off his dancing skills and the scoop on the real Lavender Gooms (she’s a real person!)

8. The Episode Titles!
Among season four’s other episode titles: “High Noon-ish,” “He Dead” and “You Can’t Handle This Episode”

9. The Pineapples!
Are you a fan of Psych? And a fan of delicious flavor? Then the perfect season premiere snack is, of course, the official fruit of Psych, the pineapple. Check out the many, many pineapple recipes at About.com and submit your own pineapple recipes to the official Psych Website.

10. The Theme Song!
The show’s promos are almost as good as their episodes. Season four’s discussion between Shawn and Gus about a new theme song for the show is a classic. Of course, Psych already features one of the most infectious TV theme songs of all time, “I Know, You Know,” by The Friendly Indians, the band of Psych creator Steve Franks.
