Printing all your important documents in human blood will save you almost half the dough as HP ink. Plus, you'll earn the respect of your coworkers, particularly IF YOU USE THE BLOOD OF YOUR ENEMIES. It's true, one time I printed an article in ninja blood and now both the pirates AND vikings do whatever I say. Oh yeah -- that's the spot, Blackbeard, keep scratching. Hey -- no laughing Lief, you're next.

Thanks to jantunes, who once printed a document in dragon blood, opening a portal to a magical land of wizards and shit.
