After the concert, the Jonas Brothers invite several girls into their dressing room, where the girls assume they're there to give the boys blow jobs. The boys have no idea what blowjobs are, and instead preach to the girls about their religious faith, and then give the girls purity rings in an attempt to encourage them to not engage in any sort of "naughty" behavior such as sex, drugs, watching "naughty TV shows", or swearing.
While the boys are successful at doing this, it is revealed that the Brothers dislike the idea of forcing the rings on the girls, wanting their careers to be about their music. Mickey Mouse, their boss and the owner of the Disney Corporation, forces them to promote the rings, as he wants to sell sex to little girls, but without parents realizing it.
