Dogg's Hamlet and Cahoot's Macbeth are two plays usually performed together. In the first, two people are building something, but while both appear to be speaking English, it turns out the words have a different meaning for each of them, as one of them is speaking Dogg. In the second play, a private production of Macbeth is interrupted by a policeman, who threatens to arrest everyone present for subversive activities; later, the actors begin speaking in Dogg. The plays explore themes of communication, the manipulation of language, and political protest.
