In school, you are taught a lot of "facts." Little, mainly worthless nuggets of information that stay in your head for decades, returning every now and then in hamfisted attempts to fill an awkward silence or — for some reason — precisely as you're attempting to fall asleep. We've all got a few too many of those random facts in our heads for no apparent reason.<br/><br/>That's when these bad boys come in. These are the types of things you don't learn in school. These are the kinds of facts that you'd be better off not knowing. Send in a squad of these ruffians to clear house if you want old, dull facts gone because they are the only facts you'll remember once they're done.
