Ecoterrorists storm an animal testing facility on tonight’s episode, but don’t worry — this quirky comedy hasn’t gone all hard-core political. Fred Armisen and Carrie Brownstein (and guest star Olivia Wilde) have a way of making these characters uniquely human and likable. And that is what makes this clever comedy — now in its fourth season — endlessly watchable. Oh, and did you see that bird in the opening sequence of last week’s premiere episode? 7 p.m. Thursday, March 6, on IFC (seattletimes.com/tvlistings).
