Verbal irony: Pretense or echoic mention?

According to the mention theory of irony put forward by Sperber and Wilson and tested by Jprgensen, Miller, and Sperber, verbal ironies are implicit echoic mentions of meaning conveying a derogatory attitude to the meaning mentioned. In their criticisms, Clark and Gerrig misrepresent mention theory. The pretense theory, which they offer as a superior alternative, might provide a plausible description of parody, but it fails to account for many types and many properties of irony proper.
