'Portlandia'

After a wonderful preview episode last month, the quirky comedy starring Carrie Brownstein and Fred Armisen is back for a third season with funny back-to-back new episodes. There's a guy who proclaims that he's "never owned a TV" discovering the current state of MTV; great musical numbers ("Change the world, one party at a time"); commercials for "natural" deodorant; and Portland "missionaries" sent to Seattle on a quest. 7 and 10 p.m. Friday on IFC (seattletimes.com/tvlistings).
