As a kid, I had a dining place mat with a map of the United States on it that showed Alaska and Hawaii in insets at the bottom. Even when it was explained to me, I absolutely refused to believe they were not depicted in true location and scale to the rest of the country. I knew for a fact that Hawaii wasn't far from the California coast and that Alaska was in some sort of bay in Mexico. Seriously.
