Make Carlyle strap Korey down to a chair and play clips of comics, nerdish films, and RPGs like WoW. After a while Korey will remember and like it. Then make him go to a convention with his new knowledge and that might work. Lol. Just kidding.
If I was to seriously answer this I would say you can't teach someone to be a nerd. It is just the way someone's personality is. My personality is very open and I welcome new things. That makes me adapt to many things. I am not getting into detail what that does or me because I did that in my blog. With nerd girls you have three different types. Those who are normal and don't care if you are a nerd or not and can not even seem like a nerd around others. That kind of nerd girl korey might be able to get. The second is those who are really nerdy. That is anything over what I previously said. The last is those who are any rank of nerd or a person posing to be a nerd who have high standerds or are there to tease. These people would probably be hot. Problem with all this is that most nerds want to hang out with people who are like them more so with girls. Because of the last statment Korey will probably never get a nerd girl.
