Monsters, Inc. Laugh Floor is a live theater show in Tomorrowland at Walt Disney World's Magic Kingdom. It's worth seeing on a time-permitting basis.
This show, inspired by the Pixar Animation film Monsters, Inc., offers an improv-style comedy show in the old Timekeeper/CircleVision theater. The show uses unseen live voice actors to overdub the on-screen monsters, allowing them to target selected audience members for jokes. Sit near the center aisle if you want to improve your chances of getting on screen.
