As kids, we all seems to get crazy thoughts that, at the time, seem smart, but are really just very stupid.
One stupid thing that I believed was that I thought the world - in real life - didn't exist in colour until colour televisions were invented. I thought everything was black, white or in the grey in between. >_<
Looking back, it's really quite a funny thought. As a generation growing up with colour TV already there, not to mention being so impressionable, it seemed only obvious that colour was not "invented" until colour TV.
So what are some crazy, stupid or otherwise funny things you used to think when you were a kid?
