The first teaser trailer for Disney*Pixar’s prequel to the 2001 hit Monsters Inc., titled Monsters University, has been released online.

In the movie, Mike (Billy Crystal) and Sully (John Goodman) are back in college, and they may not have started as the best of friends. The teaser shows off one of the college pranks Sully pulled on Mike…surely the first of many we’ll see between the two.

Disney actually released four very slightly different versions of the teaser, each with Mike saying something different in his sleep.

You can see one of them below directly from Disney, and you can check out the other three by heading to Apple, Yahoo!, and The Huffington Post. Then, if you wish, you can head to the movie’s Facebook page to vote for which of Mike’s four lines is your favorite.

The prequel’s voice cast includes Steve Buscemi, Dave Foley, Julia Sweeney, Joel Murray, and Peter Sohn, and it will be released on June 21, 2013.
