The authors take a critical language pedagogy approach to examining a 2011 controversy over disparaging comments towards Mexicans made by commentators of the British Broadcasting Corporation's automotive show Top Gear. In particular, they focus on the characterization of groups and individuals according to their nationality and examine the ubiquity of nationalism and its ability to shape our conception of culture and in turn our understandings of others as members of "X national culture." The fact that humor is often a justification for national stereotyping and that these stereotypes are also connected to racist discourse are also explored. In the second part of the article, the implications of the stereotyping debate for language classrooms are considered. The authors argue that the controversy itself can be used as a tool for critical engagement that helps students deconstruct the underlying nationalist paradigm in L2 classrooms and build greater intercultural awareness.
