The Ravenous Bugblatter Beast, a nightmarish executioner animal from Hitchhiker's Guide to the Galaxy, is described as being incredibly stupid and vicious, demanding a victim's name before devouring them. Lying about one's name sends the beast into a fury, "as there is nothing that transcends the differences between humanity and Bugblatter Bestiality like an untruth," according to the creature's Wikia page.
