What a great way to show that even one raven could throw a perfectly good theory right out the window..

**newsflash! the flight of the Bumblebee doesn't defy the laws of science after all! makes me wonder what else is possible that we may think defies science now but doesn't?*... and the Bumblebee still flies..
