I've heard (and I have a hard time envisioning this. I looked all over the net) that they use surprisingly interactive puppets to teach very young Korean children.
If we're talking North Korea, I'm surprised they don't just teach them that all children come from the Great Leader. Wait, maybe that's what they do...
I don't know what you heard about Kim, but you can't get a dolla outta him. Do cadillac no perm , you can't see. That he's a motha fudgin P.I.M.P.
