One day at Monsters Inc, Blair comes across some mounted photos of both current and previous employees. (Perhaps in a display explaining the Boggs-Waternoose Plot and how the factory made the switch to Laugh Energy.) To get warmed up for her daily job of making kids laugh, Blair does some dramatic imitations of the photos.
I considered having a few more panels where Mike walks up when she's on his photo and he says "What are you doing?" to which she nervously replies, "It's a... warm up exercise."This all started with the idea of Blair doing a rude imitation of Randall's squinty eyes.
Blair is mine but the other three belong to Pixar.
