Grinch: Fat boy ought to finishing up any time now. Talk about a recluse! He only comes out once a year, and HE never catches any flak for it! Probably lives up there to avoid the taxes! [Notices Santa leaving.] OOOpsy! Forgot about the reindeer. If I can't find a reindeer, I'll make one instead. Oh, MaaaaAAAAAX!
After the Grinch unscrews the light bulb in the town Christmas tree, all the lights in the town go dark and the Grinch starts to take off in his sled-thing. When they show a close up of him, the lights are on. Then a few seconds later, the lights are off again.
