Reason to watch: The one-hour Super Bowl episode “Stress Relief.”

What it’s about: Dwight (Rainn Wilson) decides to teach his colleagues the proper safety procedures in case of a fire, which causes considerable stress — notably to Stanley (Leslie David Baker), who suffers a mild heart attack. Michael (Steve Carell) decides on various ways to reduce office stress because, as he explains, “Nobody should have to go to work thinking this is the place I might die today. That’s what a hospital is for … is where dreams come true.”

Some of his methods are debatable, until he decides on an office roast — of himself. Meanwhile, Andy (Ed Helms) downloads a BitTorrent version of a movie starring Jack Black, Jessica Alba and Cloris Leachman.

Bottom line: The rap on hourlong “Office” episodes has tended to be consistent — that a 22-minute joke got strrrrettttched out to a 44-minute one. Not Sunday. The episode is largely brilliant, and includes some of the most inspired bits/lines in the show’s run. (Do not miss the opening sequence.) The Jack Black movie-within-a-show doesn’t quite click, but it perfectly services a side story involving Pam (Jenna Fischer) and Jim (John Krasinski).
