I was very insistent that Grand Prix was pronounced Grand PRICKS
I would argue with my parents all the time that it couldn't possible be pronounced the way they said it was.

This is kind of a fitting statment i think. I remeber being around 12 and watching the olypics, when the power lifting came on. We were watching the various events, when my mother reffered to one of them as "The Cleveland Jerk", obviously she was in fact reffering to "The Clean & Jerk" - I wonder how many years she had been calling it that.

For a very long time I believed that skydivers were just floating in the air. After all, it didn't LOOK like they were falling incredibly fast.

As a child I used to watch a bit of soccer/football on TV. I knew they had the red card, which meant you were in serious trouble and the yellow card, which meant you were in a bit of trouble. But I was also convinced there was a green card, which the referee would only get out if you'd been really good. I never did see them use it, though...
I used to be absolutely convinced thay volleyball was bollyball. I said it all the time and I guess that when I said it people didn't realized because no one ever corrected me. I finally realized that it was volleyball one day when I was reading with my dad. I came across the world and realized that it was volleyball not bollyball, I was so shocked. I wondered why no one ever corrected me and why I had never heard anyone destinctly say it with a v.

I used to believe that the Soccer Wordl Championship "Italia 90" was called so cause a game lasts 90 minuts, and not because we were actually on the year 1990.

(Australian spacific)
When we where young my father told my younger brother that he would not be allowed to go to the football (aussie rules) unless he could eat a Meat Pie with his hands without spilling any or becoming messy. (this can be quite difficult with the cheap pies that you get at the footy. He was told this to encourage better eating habbits/skills, You are not Australian unless you can do this :-)
Years later we went to see Gelong play, My brother stoped at the turn table where the ticket man stood. He wouldn't move,
My father said "Come on, other people want to get through",
"But he hasn't asked me the question yet." James replied,
Dad looked baffled, "What Question?"
"About the Pie,"
"Huh? what pie!?, come on, your holding up the queue"
"If can eat it without a knife and fork"
"Huh?, Oh... That's not really true, come on, your allowed in," said my father, then similing at the Ticket guy,

Can't believe no one put this already, since it was common knowledge among all my friends. I used to believe that the core of a golf ball was a highly toxic poison that would kill you.

When I was young I couldn't understand why on earth my mum would want to stand on a bridge with three strangers once a week - well that's what I thought she did when she "played Bridge"!

We lived just a few blocks away from a local college, and we would always go watch the basketball games. And we would run to go get something to snack on, and to be sure we didnt step onto the court, my mom always told us that if we did, we would have to play in basketball game.

All Ohio State players were from Ohio, all Michigan players were from Michigan, all Illinois players were from Illinois, all Texas players were from Texas etc. A good high school player in, say, Ohio automatically went to Ohio State and would never play in Michigan or Pennsylvania, etc.
Similarly, all Chicago Cubs players were from Chicago, all Pittsburgh Pirates players were from Pittsburgh etc.

In 1985 Boris-mania started in Germany when 17-year-old Boris Becker won Wimbledon for the first time. During the tournament my father always told me "Boris is in the quarter-final", "Boris is in the semi-final" and so on. I had no idea how tennis tournaments were organized, so I believed quarter final, semi final and final were all the ranks a player could reach in his entire career. I thought Boris was very successful reaching this in two weeks at the age of 17!!!
By the way, I believed his opponent (Kevin Curran from South Africa) was called Curren Curren.. ;)

My dad used to lay tile. He joked that he would make it to the Olympics and compete in tile-laying, and I thought there really was such an event in the Olympics.
I used to believe that the Super Bowl was actually a bowling competition. I was most puzzled as to why it was such a big deal.
i used to beleive that there were little elves inside basketballs that would jump when it hit the ground and thats what made it bounce.
I thought that soccer moms were moms that played soccer!
