Mike doesn't realised he's been turned into a moving disco ball

What's so funny? Mike doesn't realised he's been turned into a moving disco ball

'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.'
Pixar are asking fans to vote for their favourite teaser trailer .
The winner trailer will be drawn by a Pixar artist and shared exclusively with fans of the film.

Given the disco soundtrack and the fact that his classmates start dancing around Mike once he storms out of his room, its safe to assume to trailer is probably set in the Seventies.
He is unaware of his new body art, fuming: 'If you're going to prank someone, at least you can do is think of something clever.'
Voicing the trailer, Crystal had so many ideas, producers decided to release four slightly different trailers.
The nearly identical promos feature teenage Sully and Mike and their monster friends 'letting their fur down' at college before they have to work at Monsters, Inc.
Blue-haired Sully, voiced by John Goodman, is seen playing a prank on a sleeping Mike (Billy Crystal), who mutters a different sentence in each trailer.
Clutching a tube of glue, Sully sticks reflective panels on his circular friend, so he ends up looking like a disco ball.
