"Believe it or not, Twinkies have an expiration date." Perhaps Woody Harrelson's badass zombie-killing character was an eerie oracle sent to warn us about the future – a post-apocalyptic future in which we'd all be searching for the elusive last box of Twinkies on Earth. (The real horror: Parent company Hostess went bankrupt in late 2012.) Depending on your sense of humor, a case could be made for the 2009 zom-com having the funniest integrated marketing in years. Fun fact: The "spongy, yellow log of cream" that Harrelson finally gets his hands on is actually a raw, vegan replica of the tasty treat.
