After getting a lesson in improvisation at the legendary comedy workshop The Groundlings, the models are challenged to successfully deliver a mostly-improvised CoverGirl commercial, and one lucky girl, whose improv skills are superior, wins a guest starring role on "Veronica Mars." Nick Cannon ("Men In Black II") makes a guest appearance. Later, some of the models appear in a public service announcement about HIV prevention in support of KNOW HIV/AIDS, a joint venture between CBS Corporation and Viacom, in partnership with the Kaiser Family Foundation.
