When I was little I thought that animals, insects, and fish had their own houses (not just nests, I meant brick/wood/whatever houses like us xD), and when I heard that your waste in toilets go to the sea, I thought that they like magically appeared into some fish's house when they flushed it. xD

So the fish would be all, "How's it goin'- OMG!  THERE'S SOME BROWN STUFF THAT SMELLS!!1one1!!1!  WHERE DID IT COME FROM OMG.  I THINK IT'S PUFFER FISH.  RAWR.  OKAY GO AWAY NAOW.  WAIT, PUFFER THINGS DON'T SMELL.  I THINK IT'S- OMG!  WHATS THAT FLOATING YELLOW LIQUID THING.  YEAH, THATS TOTALLY A PUFFER FISH.  THE OTHER ONE WAS SO OBVIOUSLY A GOPHER.  OR JUSTIN BIEBER.  WAIT, BUT I DON'T EVEN KNOW WHO JUSTIN BIEBER IS!  THAT NAME JUST POPPED UP IN MY HEAD.  OH WELL." -swims away happily-

So, yeah. xDDD

I used to think hippos lived in my kitchen when the lights were turned out.

Yeah.

I thought that the toilet was haunted and that if I came within two feet of the bathroom the "Toilet Spirits" would get me.

...They were scary.

This thread is doing better than I thought it would.  lol

Just thought of another one.  When I was little, I always wanted a sister.  (Never worked out, by the way.  I ended up with 3 little brothers and no sisters.)  My mom told me that when she had Trenton & Nick, the older 2, I denied I had a brother.  When her & my grandma told me I had a brother, I always said, "Nuh-uh.  I have a sister.  Mommy didn't have a boy, she had a girl."  Even after they let me see the baby, I was in denial.  XD  A big letdown for a 2-3 year old girl.

I also remember thinking that Pterodactyls were called Aerodactyls. This is continueing from the post were I thought Pokemon were real.

So. When I was about seven we were doing a project on Dinosaurs and we watched this tape about the avian varieties. A bunch of poorly rendered pterodactyls appeared on the screen and I stood up in the middle of the cl*censored* and shouted,

"Guess what. I found one of those behind Pewter Museum!"

The reason I remember it so vividly is because I wasm't allowed to play with the chalk because I was 'shouting out' and 'lying'. Those were like, the most serious offences in Primary school. And since that incident I was officially Aerodactyl when we pretended to be Pokemon. Which was pretty good, because it was a step up from being a Magmar.

When I was a kid I watched Dora. I mean, what kid growing up in the Early 2000's didn't? o3o

I remember being about 5-6 years old and I'd always walk right up to the T.V. when the Map would come out. And you know how at the end, he would repeat the directions three times and then jum and the camera would zoom in onto his mouth? Well, I thought he was trying to eat me, so every time he blared out the last direction and jumped at the screen, I would shriek and run away. o3o

I also thought that everyone named Steve had a dog named Blue. And liked to draw. 

When I was little, I thought that broccoli was just tiny trees. o3o

I also used to think that if you stayed in the bathroom after flushing the toilet, a skeleton would appear in the bathtub. o.o

And then. I used to think hobo's were like.. cannibals. o.o Only I didn't know the term cannibal, so in my little single digit aged self, hobo's were people who would eat other not hobo people. ;c
