The sixth season of the show that made geeks cool. Geek culture laid out for the rest of us to observe and try and understand. Sheldon (played by Jim Parsons), Leonard (played by Johnny Galecki), Howard (played by Simon Helberg) and Raj (played by Kunal Nayyar) are friends who are all scientists and not your average, run-of-the-mill scientists, but ones that work on stuff having to do with outer space, theoretical physics, etc. Serious science. Somehow the writers of the series have managed to make them funny as opposed to the dull as dishwater you would expect. This is because as brilliant as they are is as backwards as they are when it comes to social situations or relationships. Wit, heart, jokes, sex, relationship problems, and references to sci fi movies and film are what make up the backbone of The Big Bang Theory.
