My friends were playing D&D and our DM has a system where he allows everyone to request one magical items, and he usually makes it useless by screwing us over on a detail.
GUESS WHAT?! ONE HAPPENED TO BE USEFUL! My friend asked for a bag of unlimited bullets, each with their own magical power. When you open the bag, they take effect. Well an infinite number of them have the ability to explode with fire, it doesn't hurt the bag, so instead it shoots fire and bullets from the bag, like a FIERY SHOTGUN! It's as big as a keg, but only weighs five pounds, so it's awesome.
Edit: Oh and welcome Chase! :]
