With Brave hitting theaters this weekend, Pixar has released a pair of teaser trailers for Monsters University, the prequel to 2001's Monsters Inc. The teasers are exactly the same with the exception of Sully's punch line in the beginning. Still, it's good to see Mike and Sully again.

Billy Crystal and John Goodman are back voicing Sully and Mike as the film looks at the pair's relationship during their days at the University of Fear.

Monsters University opens in theaters on June 21, 2013.
