I have two overly nerdy friends who were in an undecided argument and I'm bringing this to the mmo-c boards to find the answer. Imagine the guys from Big Bang Theory. Howard and Sheldon are battling it out. I'm Leonard because although I'm also a nerd, I am the coolest of them.
Howard: Karazhan life sized chess idea was brilliant!
Sheldon: Actually the idea first appeared in the Harry Potter series.
Leonard: They both probably got the idea from a really old book like everything else these days.
Howard & Sheldon: Shut up you noob.
