ThinkGeek is selling the 'Ring Thing,' a simple piece stainless steel jewelry that lets you perform beer-opening magic tricks at the drop of a backwards ballcap. Since my cheapo keychain bottle-cap opener died (Thanks, Dogfish Head!), I'm going to give this a go—as soon as I can find a ruler that measures in increments of 'sausages.'

Pop it on your middle finger, teeth-in, and grab the bottle firmly (but respectfully), levering your wrist up like a fop. Not a bad little bit of engineering for 10 bucks.
