LOL!
I remember when my kids discovered that their friends next door had never heard of the Alamo.
Funny thing is, I learned about the Alamo from watching TV. My parents had me watch reruns of that old Davy Crockett show. When he dies at the Alamo at the end, it was very crushing for a 7 year old, so I decided to read up about it.
I guess TV isn't ALL bad. ;-)
