On the morning of January 31, 2007, the Boston Police Department and the Boston Fire Department mistakenly identified battery-powered LED placards depicting the Mooninites, characters from the Adult Swim animated television series "Aqua Teen Hunger Force", as improvised explosive devices (IEDs), leading to a massive panic. Placed throughout Boston, Massachusetts, and the surrounding cities of Cambridge and Somerville, these devices were part of a nationwide guerrilla marketing advertising campaign for "Aqua Teen Hunger Force Colon Movie Film for Theaters", a film based on "Aqua Teen Hunger Force".
