Your child. Your friend's child. Your cousin's child. Some child that snuck in while you weren't paying attention. It's either show them movies or ignore how they're dismantling the coffee table and beating each other with couch pillows. You pick!
If you're really being honest with yourself, there's a limit on how many times you can actually enjoy A Christmas Story and It's A Wonderful Life. Sometime around 11am on Christmas Day, you'll be thankful for ANYTHING that keeps you from watching the Yule Log again. Stock up and be ready.
