While Steve Carell has said he won’t be returning as Michael Scott for The Office’s finale May 16th, word came in a couple weeks ago that “producers mounted an 11th hour effort last month to coax Carell into making a cameo.†Last night, David Letterman took the opportunity to grill Mindy Kaling on the matter, but didn’t really get anything out of her. Any guesses on whether Michael Scott makes one last appearance or not?
