On TV this week
SEASON FINALE How I Met Your Mother, 8 p.m., CBS Barney's getting married, Ted finishes the house and Marshall heads to Minnesota with Marvin. This sounds suspiciously like adult behavior.
SERIES FINALE 90210, 8 p.m., CW Prince Michael Jackson guest starring ruins the end of this series' run, but, hey, there's a performance of the Goo Goo Dolls. What is this, 1997?
SEASON FINALE 2 Broke Girls, 9 p.m., CBS Max and Caroline clean the diner, leading to finding something that could relaunch the cupcake business. They must have found the DVD for Kristen Wiig's movie Bridesmaids.
SEASON FINALE Castle, 10 p.m., ABC Castle and Beckett find a dead woman in the water tank of an apartment building. We imagine the rents will probably drop after that.
SEASON PREMIERE So You Think You Can Dance, 8 p.m., Fox Jesse Tyler Ferguson, Minnie Driver and Wayne Brady are among the guest judges this season, the show's 10th. It seems some people are still under the impression they can dance.
SEASON FINALE NCIS, 8 p.m., CBS Homeland Security goes after the team for looking for Eli David's killer. Because there's no reason for NCIS to do that.
SEASON FINALE NCIS: Los Angeles, 9 p.m., CBS Meanwhile, the NCIS team on the West Coast gets to hunt down stolen nuclear weapons. Let's see Homeland Security question that.
SEASON FINALE New Girl, 9 p.m., Fox It looks like Rob Reiner and Taylor Swift are coming to Cece's wedding. Ooh, we didn't even know Taylor and Rob were dating!
SEASON FINALE The Mindy Project, 9:30 p.m., Fox Mindy goes to Haiti with Casey for his volunteer mission. It isn't until she gets there that she realizes she was thinking of Tahiti, just like Bill Pullman in Ruthless People.
SEASON FINALE Arrow, 8 p.m., CW The hunt for the Dark Archer is on, before he ends up shooting Thea. And everyone else.
SEASON FINALE Supernatural, 9 p.m., CW Sam and Dean get one last chance to take down the Demon King. We have it on pretty good authority they will succeed somehow.
SEASON FINALE CSI: Crime Scene Investigation, 10 p.m., CBS A reporter follows the team around as they investigate some murders. The real story, though, is that Black Sabbath will be performing.
Psych, 10 p.m., USA Shawn and Gus go undercover as DJs when a radio personality ends up murdered. We hope this isn't based on Bubba's legal feud with MJ.
SEASON FINALE The Big Bang Theory, 8 p.m., CBS Leonard gets a great job offer overseas, but because Sheldon and Penny are so codependent, he's conflicted about it. Here's a hint, Lenny: Take the money and run for the far reaches of the globe.
SEASON FINALE The Vampire Diaries, 8 p.m., CW Ghosts show up on graduation day, and we don't mean the ex-girlfriend kind. Well, maybe.
SEASON FINALE American Idol, 8 p.m., Fox We learn which of the no-names wins Season 12. Say so long to the entire panel, too. Or Randy Jackson, at least. See The Juice*, Page 38.
SEASON FINALE Grey's Anatomy, 9 p.m., ABC A storm fills up the hospital, so of course one of the doctors ends up in grave danger, too. Can we get back to Karev seeking revenge? That's what we call a storyline.
SEASON FINALE Beauty and the Beast, 9 p.m., CW Cat has family problems. Beyond digging a guy like Vincent, that is.
SERIES FINALE The Office, 9 p.m., NBC Time to close up shop at Dunder Mifflin. The show that made Scranton a tourist destination ends after nine seasons. Pass the beets, please.
SEASON FINALE Elementary, 9 p.m., CBS This is a wild guess, but we're betting Moriarty gives Sherlock and Watson a hard time.
SEASON FINALE Scandal, 10 p.m., ABC Surprise! Olivia has to deal with another scandal. At least there's job security in the White House.
Undercover Boss, 8 p.m., CBS Last week was the season finale, sure, but we have lots more stuff to watch. Those camera crews don't hang out for weeks at a time for nothing.
SEASON FINALE Nikita, 8 p.m., CW Nikita must choose between saving Michael or herself. From a ratings standpoint, this is a no-brainer.
Merlin, 10 p.m., SyFy Mordred pleads with Arthur to spare the life of a would-be assassin Arthur has sentenced to death. Those two probably are going to agree to disagree.
The Moment, 11 p.m., USA Jennifer Lopez's choreographer helps another choreographer try to become the choreographer for a pop band made by Madonna's choreographer. That's a lot of choreography.
