The Killer Underpants is a humorous and surreal children's novel, likely part of a series (such as The Jiggy McCue series). The title introduces an absurd, comical premise: ordinary underpants that somehow become a source of trouble or are possessed of malicious intent. The plot would follow the protagonist dealing with the chaos and embarrassment caused by this bizarre piece of clothing. The book is pure, anarchic comedy, driven by ridiculous situations and a celebration of the ridiculous.
