booing

Black and white single-panel cartoon.
A three-eyed fanged monster wearing a graduation cap and gown is standing behind a lectern with a university crest on it, addressing an audience of students (visible only as tasseled mortarboards) at a commencement ceremony.
Caption: "And, as you head out into the world, your fresh, meaty torsos will be ripped apart and roasted to feed your new alien overlords -- wait, why are you all booing?"
