Humor is arguably an essential part of Gonzo journalism, yet the topic has only recently received academic attention. This chapter contributes to emerging scholarship by describing aspects of Hunter S. Thompson's Gonzo through humor theory. We illustrate our discussion by scrutinizing three contemporary cases of Gonzo in Finnish media. Our thesis is that the most prominent feature of Gonzo humor is edgework-a volatile participatory self-reflective literary style of immersive reporting that entails dramatic irony, explicit mockery, and hoaxing. Edgework-voluntary risk taking-is not in itself necessarily humorous, but is accompanied in Gonzo with the humorous elements of dramatic irony, vivid mockery and brutal hoaxing. Gonzo can highlight false promises, hypocrisy and incompetence in relation to socially important issues (e.g. drug culture, politics, journalism) and thereby fulfill the informative and critical functions of journalism. Yet hoaxing and hyperbole undermines, for some audiences, the core value of journalism: the struggle for the truth.
