Much previous scholarly work has noted the gendered nature of humor and the notion that women use comedy in a different way than do their male peers. Drawing on prior work on gender and humor, and my ethnographic work on teen girl cultures, I explore in this article how young women utilize popular cultural texts as well as everyday and staged comedy as part of a gendered resource that provides potential sites for sex-gender transgression and conformity. Through a series of vignettes, I explore how girls do funny and provide a backdrop to perform youthful gendered identities, as well as establish, maintain, and transgress cultural and social boundaries. Moving on to explore young women and stand-up I question the potential in mobilizing humor as an educational resource and a site in which to explore sex-gender norms with young people.
