In South Park’s episode entitled "Smug Alert," which aired originally on Comedy Central on Mar. 29, 2006, Stan persuades all the citizens of South Park to buy hybrid cars. A disaster of epic proportions threatens the town and Stan is to blame—just as everyone starts to feel really good about what they’re doing to help save the earth, scientists discover a stormy, dark mass accumulating over the town. It’s a storm of smugness emanating from the new hybrid drivers of South Park, the general population of San Francisco (who enjoy the smell of their own farts), and George Clooney’s 2006 Oscar acceptance speech.
