Watch it

“Community” (8 p.m., NBC). Britta and Professor Slater compete for Jeff’s affections in the season finale. The show has rebounded nicely from early-season doldrums, let’s see if it can go out on a high note.

“Parks and Recreation” (8:30 p.m., NBC). In the season finale, auditor Ben (Adam Scott) rains on Leslie’s parade when she wants to hold a children’s concert. And Mark makes a big decision. (Hint: He’s not coming back next season.) Enjoy “Parks and Rec” while you can — it won’t be back until November or so.

“The Office” (9 p.m., NBC). In the season finale, Jo (Kathy Bates) storms into town to track down the whistle-blower who exposed Sabre’s flaming printers. Andy cowers.

“30 Rock” (9:30 p.m., NBC). Yet another season finale; in this one, Liz scrambles to attend three weddings in one day and meets — could it be? — the love of her life. Matt Damon guest stars as the “real” Astronaut Mike Dexter. Meanwhile, Jack has to choose between his two lady friends.

Record it

“Fringe” (9 p.m., Fox). The two-part season finale concludes with all the players in the parallel universes coming into contact with each other and duking it out. Well, at least the Olivias duke it out. Should be awesome, with the fate of two dimensions hanging in the balance.

“House Hunters” (10 p.m., HGTV). A couple looks for a home near the beach on the Jersey Shore. Oooooh, maybe it’s Ronnie and Sammi!

“Late Show with David Letterman” (11:35 p.m., CBS). The regular guests are lame, but Band of Horses perform, and they’re super cool.

Skip it

“Grey’s Anatomy” (9 p.m., ABC). Who gets shot in the two-hour season finale? Better yet, who cares anymore?
