I remember being confused about The Flintstones thing as a kid. In my head I always pictured it as it is now, but what confused me was when I actually payed attention and spelled it out. It was The Flinstones and I could not wrap my head around it. It didn't make sense at all.
On another note I used to watch The Lord of the Rings trilogy monthly, I had the entire thing memorized and it was definitely "Run, you fools".
