10 - 2: Smug Alert!

Kyle's dad buys a new hybrid car. This makes him feel smug, and he moves his family to San Francisco because people in South Park have no respect for the environment. To get Kyle back, Stan convinces people in South Park to buy hybrid cars, too. But when they do, it leads to extreme weather conditions in both San Francisco and South Park.
