This is my best explanation. I have met all those people on that show. PhD candidates can actually be that annoying and overly intellectual/antisocial. Having said all that, I still don’t like the show. The bits are too fake, as is the premise. In real life, the super hot girl would just ignore them completely and complain to her lead guitarist boyfriend that she lives next to geeks. As a nerd with a nerd’s job, which may put me in some supernerd category, I may or may not have lived out this scenario a thousand times.
As always, love the show.
