We'll admit it: Every now and again, we love a good prank. Tricking people can be totally hilarious — but then again, sometimes it just goes slightly too far.
Take, for instance, this young man. He decides to play a prank on his sister involving himself, a blender, and a bloodied hand. It's a gruesome trick that gets the desired effect he was going for, but seeing it on camera will make you cringe — and hope that his sister gets a chance to exact sweet, sweet revenge.
