If you're looking to wage delicious warfare on your officemates, why not buy one of these sweet double-barrel marshmallow guns from ThinkGeek?

With a capacity of 50 miniature marshmallows split across two barrels, this puppy can let you live out your Dick Cheney fantasies without any trips to the hospital...unless your friends are diabetic (get new friends).

The pump-action firing system is simple and efficient, letting you spray marshmallows up to 30 feet. Accuracy isn't quite as good, but with a magazine of 50 shots it's more about volume. And when you're done, you can just eat the spent bullets.

This is what Rambo would bring to a campfire.
