This paper examines the relation between novel metaphor and humor in political satire. In order to do so, two corpora, one consisting of mainstream broadcast journalism, the other of the media that satirize it, are examined. The analysis of both corpora shows that satire tends to reiterate the traditional news source. However, satire does present distinctive patterns of variation. The analysis reveals that at least a part of satirical comedy works by exploiting the conceptual qualities left unused in traditional political metaphors. Notwithstanding, there are boundaries to the directions which satirical extensions may take. In this corpus, the prevalent method is metaphorical extension.
