They teach you a lot of "facts" in school. Little, mostly useless tidbits of information that you'll never use but stick around in your head for decades, resurfacing every now and then in hamfisted attempts at filling awkward silence or -- for some reason -- right as you're trying to fall asleep. We've all got a few too many of those little factoids taking up space in our head for no good reason.

That's when you send in these bad boys. These are the kinds of facts they don't teach you in school. The kinds of facts that, heck, you're probably better off not knowing. If you want old, boring facts gone, send in a team of these ruffians to clear house, because when they're done, these are the only facts you're gonna remember.
