A friend of mine is a buyer for Drugstore.com. She found this fun little toy that's great in hot chocolate weather or around the campfire in Summer. She even got it on Leno, Conan, and  Letterman - the Marshmallow Shooter.

She brought a prototype to a neighborhood dinner a few months ago and it was crazed. The adults were having a little too much fun with it shooting about 30 feet across the house.

Sure, you could build one of these yourself, but I doubt you'd get the same quality. It shoots rapid-fire mini-marshmallows or foam pellets. At work people like to get fun and funny things to break the stress. The best part is getting to eat the ammunition when the fun is over. 

I have to get a few of these... too bad I forgot about it for Christmas- there's always next year though.
