Holiday Season One-Shot Ideas

Hopefully no one in my party sees this, but I'm making a holiday one shot for my party. I'll make most of it on my own, but ideas can't hurt. This can also serve as a place for any other DMs to get ideas (if this has been done, let me know). I have a party of 5, all at level 2. I just wanted to get some outside opinions from more experienced people than myself since I've only been DMing for a few months (it's going well so far). I'm playing in 2014 5th edition.

Please share any and all ideas you have, I really want this to be a place where anyone can get ideas.
