Open a beer bottle with a sheet of paper
A friend sent me this link, knowing full well I'll never, ever need it (I carry a bottle opener on my keyring in case of such emergencies). But, for those of you not always equipped with beer tools, this is a cheap, simple solution.
It is also worth noting that it's a much safer solution than a: Using your teeth and chipping off the enamel, or b: Slamming your beer on the side of a table and either breaking the table, your bottle or several bones in your hand.
So here we have it. In just 2 minutes you'll forever know a way to impress every single one of your alcoholic friends. I've also posted the latest parody currently doing the rounds. Mucho fun.
