The writer of Legally Blonde was a student at James Madison University and she based the movie off of her friend who was a member of JMU's Delta Gamma chapter, Epsilon Nu. The sorority in the movie gets it's name from the combination of the sorority itself and the chapter.... Delta (Gamma) (Epsilon) Nu. Delta Gamma's crest appears in the movie at some point, but it has Bruiser's head in the center of it.
