We've had reports that some hooligan has been placing a "Flaming Paper Bag" filled with poo on glitches doorsteps this holiday season. At least ten victims have been found so far, and the only clue seems to be an IM saying "DING DONG (Check your front door!)"
Whatever you do, do NOT, I repeat, DO NOT STOMP ON THE FLAMING PAPER BAG!! It's not really on fire. Instead, try to enjoy the spirit of the joke, and go fill up your new large bag!
Happy Zilloween!
