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.
A childhood belief about sport

others believed things like this
- I thought that soccer moms were moms that played soccer!Anon
- I always thought that after 1999 it would be 1990 again, but with different months and days of the week
— optional - I got the 1990s and 1900s mixed up, so I thought people wore that fancy old-fashioned garb in the 1990's.Anon
- I used to believe that the game The Legend of Zelda: Twilight Princess was the longest game ever.Anon
- Abba - Happy New Year
