I just saw Monsters University and I loved it!

Without giving away the story, let's just say that GREEK LIFE features prominantly in the story. I loved how they co-opted some real Greek letters and changed them a bit...for example, Sigma is now Slugma. Omicron is an Oozma, and then they took some liberties where a P stands for Python. Ha ha!
P.S. I am sure that more than one USC (the California one, not South Carolina) alum worked on this movie, since a number of USC Greek houses are former ambassador residences:
GREEK ROW
Once the home of Monster Embassies, MU's storied Greek Row is the birthplace of scholars, statesmen, and champion scarers.
