NBC has pulled Community from the network's midseason schedule so we can all continue to enjoy the magic of the wretched new sitcom, Whitney.  In fairness, NBC has given Dan Harmon's hilarious and brilliant sitcom over two seasons to find an audience and that audience has never come.  But the ones who have shown up (i.e. smart people) have been rewarded with references so clever that sometime they cannot be seen with the naked eye...or at least not in a single episode (or even a single TV series).Case in point: a Community fan recently noticed that the show had directly referenced Tim Burton's Beetlejuice once per season for the past three seasons, which would of course complete the eponymous character's summoning chant, "Beetlejuice, Beetlejuice, Beetlejuice."  On any other show, that would simply be a coincidence and a writer's room that liked the 1988 comedy as a go-to reference.  On Community, it's par for the course.  Hit the jump to check out the proof of Beetlejuice summoning and hope that a Michael Keaton guest spot is on the way.  Community airs at 8/7c on NBC.  Tell your friends.-
