I used to believe that the world was greyscale up until the late 40s. All the movies from before then were black & white (I had seen alot of them, my parents are big marx bros fans)
then one day I asked my dad "Back when the world was black & white, what color was the ocean?"
It was about a year or so before i realized why he was laughing so hard.
