It looks like I'm first to make a Christmas sig (what do I know, I've been playing my Wii all the time). My dad and I had just bought our tree And he commented on everyone's decorations saying "Look, we could just steal that and get it free. We'd have the most amazing house!" After a few minutes of that, with me saying, "No." to each one, we come to a house with an inflatable The Grinch. He said, "We could switch people's decorations around at 3 AM and when they wake up and look, they'll be like, 'HEY! YOU STOLE MY GRINCH!!!'" And so my sig is
"HEY! YOU STOLE MY GRINCH!!!"
