Optical Illusion - Bothersome Fly Tie

Don't you hate it when a fly lands on your face, between your eyes, and your hands are full. There are tricks to the trade when this happens, usually starting with an outward exhalation blowing upwards, enough to make your hair move and your nose becomes moist with the hot air that comes out. But its not enough and the fly sits there, rubbing its little hands together, laughing at you... Or you assume it is, its so blurry you can't quite see or hear it. But its there, like torture, those dirty little feet just sitting on your nose, who knows where its been. Knowing it can't be swat at, it starts to kiss your head. That's right the same dirty mouth that was touching things you don't even want to think about, is now intimately touching your face! So you get this bright and desperate idea, you'll smash the fly with your own head! It will work, just line yourself up with a post and just one fast hit, smash your head straight into it. The fly is gone, it never saw it coming. You are victorious! Bleeding and a bit delirious, but happy, you got the fly, and everyone will just look at you like your a crazy person. But that doesn't matter because you got it! Congratulations! You are a winner!
