You graduated from middle school and found your way to a desk job, but that doesn't mean you have to leave rubber-band-powered projectile launchers behind. YouTube's mist8k is here to show us how to build three weapons of mass distraction, using stuff you've already got at your desk. Now (goofing off at) work can be fun!
For what it's worth, mist8k definitely seems like the kind of guy who'd make for an awesome coworker. You could build an arsenal of pen crossbows, paper wad launchers, and actually-dangerous-looking pen cannons, and totally ambush the accounts payable department.
And when the boss discovers the supply closet's been raided and there's a snowfall of broken rubber bands around your desks, you'll both be fired, and no number of catapult attacks will change that. Oh well—more time for hijinks! [YouTube]
