Not since the days of Frasier or Seinfeld has a sitcom remained as consistently funny over the seasons as The Big Bang Theory has. This group of young and very bright scientists have varying degrees of social skills from little to none and that has reaped plenty of laughs for viewers.  Somehow these science nerds have made friends with the pretty girl next door who is not in anyway near an astrophysicist like the boys, yet they have taken her in to their group. This clash of the ultra bright with a person of average intelligence brings about plenty of laughs. Add in the guys in the dating world and out there in the world in general.
