DON'T MISS: "The Office" series finale -- It began as a modest adaptation of a British classic, then came into its own. Now, after nine seasons of workplace insanity, the Dunder Mifflin gang bids farewell in a 1 hour-and-15 minute episode that figures to provoke both laughter and tears. Here's hoping that Dwight, Jim and Pam (Rainn Wilson, John Krasinski and Jenna Fischer) and their pals get a proper send-off. 9 p.m. Thursday, NBC.

SUNDAY: In the Season 2 finale of "Once Upon a Time," the magical town of Storybrooke is on the verge of imploding. Next stop, Neverland? 8 p.m., ABC.
