Coffee is no laughing matter. “You have to go in with the graveness and seriousness of a court date, of a wedding, of a funeral,” says Carrie Brownstein, who joined her Portlandia costar Fred Armisen on an episode of the Cooking Channel’s web series “You’re Eating it Wrong.” The video is light on actual tips for preparation, focusing more on coffee shop etiquette: how to order, tip and engage in serious conversation with a friend by using your mug as a prop to convey the gravity of what you’re saying. Armisen and Brownstein appeared on the show to promote The Portlandia Cookbook, which features real recipes inspired by the absurd food-related sketches on their show (chickens raised on an organic cult, to name just one example). Portlandia has, not surprisingly, taken on coffee as one of its Portland-centric parodies.
