16 people share the biggest 'plain lies' they believed as kids.

Doesn't everyone know that there's an immortal fairy who collects baby teeth and it's illegal to drive a car with the light on?

Sometimes adults have to bend the truth to get their kids to follow the rules, but what happens when you assume Santa saw you cheat on that Algebra test for a bit too long? So, when a Reddit user asked, 'What things were you told growing up that were just plain lies?' people were ready to share the funniest, weirdest, over all worst false facts they once fell for.

When I was about 6 or 7 years old, I was out in my backyard digging for treasure, as kids do, when I found a dirty penny. I excitedly took my treasure inside to clean it in the sink, when, to my horror, I dropped my treasure down the drain.

I ran to my mom and tearfully explained to her that my Penny went all the way to China. Now you'd think the story would end there, but it's just the beginning. About a week later I got a letter in the mail. I'm 6, so this is a big deal.

This has never happened before. So I opened the letter in front of my Mom and brothers and started reading the contents out loud. It was a very official sounding declaration from the president of the Chinese Government that they had found my Penny and, from analyzing the fingerprints, had determined the Penny belonged to me.

There was also an identical copy of the letter in characters I couldn't recognize, and of course, my Penny taped to the letter. Took that Penny and letter to show and tell and held onto it for years.

As I got older I figured out santa and the Easter bunny were fake on my own, but man was I disappointed when I was told that my 'China Penny' wasn't real. - nanaacer
