Monsters, Inc. Laugh Floor is a live theater show in Tomorrowland at Walt Disney World's Magic Kingdom. While it's not the best, it is also recommended.
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.
