Dumb/Funny Things That You Thought Were True When You Were a Kid....

Prompted by a discussion that I had with some friends last night, what were some of the dumb things that you thought were true when you were a kid? For example, a lot of kids thought that there were little people inside radios who performed the songs etc.
I'd forgotten all about this until last night...
When I was a kid we had pet goldfish that my older brother named Simon and Garfunkle. Simon was the traditional orange colour and Garfunkle was white with orange blotches. I was really young, probably like 5 years old but I didn't realize that "Simon" and "Garfunkle" were their names, I thought that's what kind of fish that they were. For an embarrassingly long time (like maybe until I was 10!) I referred to every orange goldfish as a Simon. My parents never corrected me because they assumed I was being cute by remembering my pet goldfish...like we'd go into a pet store and I'd say "Look at all the Simons!"
To make matters worse, I was aware of the band Simon & Garfunkle but I never clued into the fact that those were their names...I thought they named their band after the types of fish.

I also realized when I was like 27 that the song "I saw mommy kissing santa clause" wasn't about the mom cheating on the dad with santa. The dad was dressed as santa.
I learned my mistake when, after swimming during a vacation to the Ozarks, my aunt told me to rinse off in the "public" shower and I was like, "but we are Catholics, not Publics!" She started laughing mercilessly and I immediately recognized my mistake (I think I was like 5 or 6 years old). I swore my aunt to secrecy but she immediately went and told my mom and I was briefly the cause of much laughter amongst my whole extended family.
So I learned that the world was not quite the way I thought it was, and not to trust my gossipy aunt all in the same day.
nah really
I always thought their was someone somewhere watching the traffic lights and switched them at the right time cuz I noticed they were switch when we approached and there was no cars coming from the other street.

Thought "play it by ear" was "play it by year"
Thought "last ditch effort" was "last stitch effort"
Thought George Foreman was some dude who sold grills, didn't know he was a boxer.
It hasn't been useful yet, but I know in my heart it will be someday.
2) When I was about 6 or so I figured out, all on my own, that (SPOILER) Santa Claus isn't real. I mean, flying reindeer? Come on, I'm smarter than that; plus we didn't even have a chimney, right? But that did leave unanswered the question of who was actually giving us those gifts every year. My brilliant little-kid theory was that they must let all the burglars out of jail on Christmas Eve to break into everyone's house and leave presents.
