'Sex Signals'
Courtney Abbott and DeRante Parker, an acting group from Chicago, Ill, perform their skit during a "Sex Signals" event Sept. 2, 2010, at Ellsworth Air Force Base, S.D. Through improvisation and audience interaction, the play explores how social pressures, unrealistic fantasies, power inequity and false preconceptions of the other sex all contribute to the tensions often found in dating.
