High-five! Low-five! Gimme some skin! It's the weekend, you guys, and with it comes the usual array of promising TV treats. Check it:

What to watch on Friday, February 17...

9pm, Fox
Things may not be what they seem when Olivia discovers a link between a mental patient and a series of murders. Or maybe they are what they seem? I don't know. Your move, Fringe.

8pm, CW
In "Origins," Nikita learns more about the night she was arrested. Elsewhere, Alex admits her true identity at a press conference. Pretty typical spy drama, basically.

9pm, CW
In "Repo Man," a serial killing demon resurfaces for another killing spree. Meanwhile Sam and Dean visit a man who's been possessed by that demon in the past in order to gain insight on the demon's M.O. (You know, besides texting at the movies and turning without signaling).

10pm, Starz
Spartacus: Vengeance
Tonight Crixus becomes separated from the group while Spartacus attempts to lead survivors through the woods to safety. Meanwhile in slightly more clothed news, Lucretia attempts to seek favor with a high-ranking Roman by digging into Ilithyia's past.

What to watch on Sunday, February 19...

500th EPISODE, 8pm, Fox
The Simpsons
Has it really only been 500 episodes? I would've guessed more in the six-figure range, but anyway: Tonight the Simpsons find themselves banished from Springfield and forced to live in an off-the-grid, post-apocalyptic shanty town called "The Outlands." Here's to 500 more!

Eastbound & Down
Season 3 picks up some time after the events of the Season 2 finale, so when we meet Kenny he's already in Myrtle Beach playing minor league baseball and April's planning their son's first birthday party. But who cares: KENNY M.F.in' POWERS is BACK.

Life's Too Short
Hey look, it's the eagerly awaited premiere of the new Gervais-Merchant mockumentary series, Life's Too Short! Owing more to Extras than The Office, this one follows real-life little person actor Warwick Davis as he deals with a crumbling marriage, bad job prospects, and partners Ricky Gervais and Stephen Merchant who take meetings with celebrities looking to play themselves in a future show. In tonight's premiere: Noted comic actor Liam Neeson swings by to pitch his comedy chops.

The Amazing Race
The 20th season of the venerable CBS reality show returns tonight with 11 new teams of easily definable "types," including Big Brother couple Rachel and Brendan. In tonight's premiere the teams must skydive from 10,000 feet. That's unexpected! Not really.

8pm, ABC
Once Upon a Time
In "What Happened to Frederick," David comes clean to Kathryn about his affair with Mary Margaret, plus Prince Charming pauses his search for Snow White in order to help Abigail find something she's lost.

9pm, AMC
The Walking Dead
Picking up where last week's episode left off, tonight Lori will encounter some trouble on the road after crashing the car. Meanwhile Rick, Glenn, and Hershel face some unexpected consequences of their saloon shoot-out.
