Watch it

“Survivor: Heroes vs. Villains” (8 p.m., CBS). Has Russell finally outsmarted himself? He doesn’t really have any allies left, unless he can convince Rupert and Colby to join him. But they aren’t that stupid, are they?

“Fringe” (9 p.m., Fox). This series is quickly becoming what “The X-Files” should have been, full of conspiracies and monsters of the week while slowly but surely advancing the main mystery. Tonight’s the first part of the two-part season finale, and guess who showed up from the alternate universe? The gang will cross over into that alterna-world for a showdown with William Bell (Leonard Nimoy). Wow, this should be good.

“House Hunters International” (11 p.m., HGTV). A British couple look for a condo in Bulgaria. Seriously. I’m totally watching.

Cool music

“The Colbert Report” (11:30 p.m., Comedy Central). Musical guests The Hold Steady. They’re super cool, and I like their new album. (Yes, I still buy albums.)

“Late Show with David Letterman” (11:35 p.m., CBS). Musical guests The National. And they’re also super cool and I like their new album too.

Record it

“Community” (8 p.m., NBC). Wait, when did this show become funny? I tuned in last week for the first time in months, and was shocked at how hilarious it was. I’ll say it now: That paintball episode was one of the funniest half hours of the year. Let’s see if they can pull it off again.

“Parks and Recreation” (8:30 p.m., NBC). Dum dum dum! Two state auditors arrive at City Hall, intent to slash budgets. And the auditors? Rob Lowe and Adam Scott, who’ll both become regulars next season.  Awesome.

“The Office” (9 p.m., NBC). Jim and Pam finally look like real new parents when their baby keeps them up all night, and Dwight backs out of his baby contract with Angela. Uh oh, you don’t want to cross Angela.

“30 Rock” (9:30 p.m., NBC). It’s guest-star-o-rama as Liz looks for a wedding date and Jack tries to choose between two girlfriends. Look for Jon Hamm, Jason Sudeikis, Michael Sheen and Dean Winters (woo hoo!), along with Elizabeth Banks and Julianne Moore.

“The Legends of Robin Hood with Olly Steeds” (8 p.m., Discovery). So how would a medieval outlaw have lived? Find out and learn more about the various legends that comprise the modern Robin Hood story.

“Supernatural” (9 p.m., The CW). The season finale brings about the Apocalypse. Wow, that’ll set the bar high for next season.

Skip it

“The Marriage Ref” (10 p.m., NBC). The judges are Howie Mandel and Bette Midler. Just shoot me now.
