This is what we found on Wikipedia regarding the Comedy Stop:

Black comedy, also known as black humor, bleak comedy, dark comedy, dark humor, gallows humor or morbid 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."

Black comedy differs from both blue comedy—which focuses more on crude topics such as nudity, sex, and body fluids—and from straightforward obscenity. Whereas the term black comedy is a relatively broad term covering humor relating to many serious subjects, gallows humor tends to be used more specifically in relation to death, or situations that are reminiscent of dying. Black humor can occasionally be related to the grotesque genre. Literary critics have associated black comedy and black humor with authors as early as the ancient Greeks with Aristophanes.
