Erving Goffman is one of the most important sociologists of the 20th century. Popular textbooks in sociology (e.g., Giddens, Duneier, and Appelbaum 2005; Macionis 2007) and social psychology (e.g., Aronson, Wilson, and Akert 2006; Cahill 2007; DeLamater and Myers 2007) devote large sections and entire chapters to Goffman's ideas concerning the presentation of self, face-work, the management of stigma and framing, among others. However, with the exception of Brown (2003), no published teaching articles or notes exist that offer in-class teaching techniques concerning Goffmanian sociology. These authors feel that sociology instructors need more teaching techniques concerning Goffmanian sociology in order to enliven the material and make it relevant to students' ordinary behaviors and everyday lives. To this end, the authors discuss in this note the teaching technique they call the "shirt-weenie" demonstration. They found this demonstration helpful in teaching social psychology undergraduates the power of face-work and tact in influencing and structuring their own individual behavior.
