Strictly speaking, this trio earned their fame on television, not at the multiplex, but Aqua Teen Hunger Force Colon Movie Film for Theaters made them into stars of the silver screen - and besides, the distinction feels almost petty. Any list about walking, talking, food items would be incomplete without these guys.
If you're familiar enough with the Aqua Teen show on Adult Swim, you probably remember that Shake, Frylock, and Meatwad got their start fighting crime before unceremoniously dropping their vocation because, well, it just didn't pay.
At that point, each ten minute installment devolved into random adventures involving the Mooninites, the Cybernetic Ghost of Christmas Past from the Future, Romulox, and an entire rogues' gallery of other characters. No overarching narrative here, just fast food staples engaging in wacky hijinx and making life miserable for their poor neighbor, Carl.
