The boys are back, as Psych returns with new season five episodes tonight (10PM ET, USA Network). It’s a change-up for the show, which has aired on Friday nights since its premiere in 2006, but an hour of Shawn (James Roday) and Gus (Dule Hill) shenanigans is certainly something to look forward to mid-week.

Tonight’s episode is a gem — one of the most fun episodes of season four so far — as WWE star John Cena guest stars as Ewen, Juliet’s brother, a military man who’s hiding a big secret from his sis, which leads Shawn to assume Ewen is possibly involved in a murder.

The episode’s also a pivotal one for Shawn and girlfriend Abigail (guest star Rachael Leigh Cook);  let’s just say things might be looking up for “Shawniet” fans …

Meanwhile, the Psych devoted who’d like to see the gang in action live should enter USA’s sweepstakes to win a trip to the Psych set, which includes lunch with the cast and signed scripts. Sweet.

And one more Psych note: Send get well soon thoughts to James Roday, who had a little appendectomy surgery last weekend.
