Ladies and gentlemen of the jury, I give you exhibit A as to the difference between geeks and nerds. I can appreciate the time and effort put into creating a costume that can actually transform from a car into a robot, but I can't condone it. If I was 10, I would be excited. If these people built these for their 10 year old kids, that would be different. The fact they made these for themselves, to show off to other nerds, and to put it onto the internet...that's just sad.
The other difference between geeks and nerds? Most geeks are not living in their parent's basements in their thirties and have had sex. You can't say that for these guys.
