Black comedy, also known as dark comedy, morbid humor, gallows humor, black humor, or dark humor, is a style of comedy that makes light of subject matter that is generally considered taboo, particularly subjects that are normally considered serious or painful to discuss. Writers and comedians often use it as a tool for exploring vulgar issues by provoking discomfort, serious thought, and amusement for their audience. Thus, in fiction, for example, the term black comedy can also refer to a genre in which dark humor is a core component. Cartoonist Charles Addams was famous for such humor, e.g. depicting a boy decorating his bedroom with stolen warning signs including "NO DIVING – POOL EMPTY", "STOP – BRIDGE OUT" and "SPRING CONDEMNED."
