Bad Teacher
There was one kid in our class who was… not all there, most of the time. The professor managed to convince him that 1) the reason old movies are in black and white is because colors hadn’t been invented yet, and they were invented by a man named Roy G. Biv.
And 2) the Earth is flat, because if you stand on one side of a room and point downward, and someone else stands on the other side of the room and points downward, you’re not pointing at the same place. Story credit: Reddit / Twyll
