Before they scared children to generate energy, one-eyed green monster Mike (Billy Crystal) and fuzzy blue guy Sulley (John Goodman) went to college. This, apparently, involved Sulley turning Mike, who delivers a different one liner in each of the teasers, into a disco ball.

Like 2010’s “Toy Story 3,” enough time has gone by that the kids who loved “Monsters, Inc.” when it first came out are college-aged. Pixar certainly knows how to tap into our need for nostalgia.

“Monsters University” is due out in June 2013. Watch two teasers below, one over at Apple and another at the Huffington Post.
