"The House Bunny" - Not so funny?

In movies, sororities and the girls in them are typically portrayed as slutty, popular, party girls.  One of these movies is the well-known comedy "The House Bunny".  In this movie, a former resident of the Playboy Mansion takes a "reject" sorority made up of "weird" girls under her wing and becomes their house mother.  Or rather, under her paws.  (Get it?  The House BUNNY?)  After the typical trials and tribulations that girls go through in order to become popular, the sorority reaches the high status that they so yearned for, under their house mother's care.

Now, throughout the movie the house mother and former Playmate, played by Ana Ferris, teaches her sorority girls how to be stereotypically feminine/slutty sorority girls.  But why was it not good enough for them to just be themselves?  It is my opinion that movies like "The House Bunny", however hilarious they may be, are giving sororities the wrong idea.  After seeing this movie, many sororities undoubtedly tried to replicate the crazy parties that were advertised or to act the way Ana Ferris' character tried to get her girls to act.  They also may be more likely to reject those "weird" girls.

Sororities already have so many negative stereotypes attached to them; movies like "The House Bunny", although humorous, are only adding to the problem!
