The Boston bomb scare occurred on Wednesday, January 31, 2007, after the Boston Police Department and the Boston Fire Department mistakenly identified battery-powered LED placards resembling the Mooninites from Aqua Teen Hunger Force as improvised explosive devices. Placed throughout Boston, Massachusetts, and the surrounding cities of Cambridge and Somerville, these devices were part of a guerrilla marketing advertising campaign for Aqua Teen Hunger Force Colon Movie Film for Theaters.
