Laura Little has written "Just a Joke: Defamatory Humor and Incongruity's Promise" (available at SSRN), which explores the ways in which courts have addressed "humour" in US and Australian defamation law. The topic can be of particular interest for entertainment lawyers who are called on to review and assess potential liability for jokes contained in screenplays, written materials (such as books or columns) and audio-visual projects.
