One day when I was about 6 years old, I was watching the weather and I noticed on the bottom of the screen it said, "Skycast: Green".
Being so young and hearing that when the sky turned green, tornadoes were likely to happen, I started crying my eyes out.
My mom told me, "They don't mean the sky is actually green; they just mean there's not that much pollen in the air. Now calm down!"
That confused the crap outta me for a year or two. :P
