House Bunny centers on a Playboy bunny (Faris) who gets kicked out of the Playboy Mansion and becomes the house mother to the lamest sorority on campus.
McPhee plays a pregnant hippy, while Stone is president of the sorority. Willis plays an insecure young woman who wears a backbrace even though she could have had it removed years ago. Dennings portrays a pierced women's studies feminist, and Goodman plays the sister who keeps switching majors and should have graduated years ago. Wright is a conniving young woman from the popular sorority.
