There really are things that go bump in the night, but apparently that's just the sound of them studying for finals.

On the eve of their adventurous new movie "Brave" Disney and Pixar are giving us a sneak peak at their first-ever prequel "Monsters University," which precedes 2001's beloved "Monsters Inc." by about a decade, as evidenced by a slim-trim version of John Goodman's friendly furry Sulley.

This new chapter in the "Monsters" universe takes Sulley back to his college years where he first met green gasbag Mike Wazowski (Billy Crystal) and presumably did keg stands, games of freshman dorm Assassin, along with copious amounts of Adderall to get through his all-nighter cram sessions.

The four trailers are all essentially the same, except for the line Crystal says while asleep in his dormroom.

"Billy Crystal's an amazing comedic actor," said the movie's director Dan Scanlon in a Disney press release. "He gave us so much fun material, we decided to cut four slightly different versions of the trailer. We are so happy to have him back as Mike!"

You can see get initiated into the four iterations below, and officially enroll in "Monsters University" when it's released next summer on June 21, 2013. We're still applying for financial aid.
