Yup. And there are other examples. Liz Lemon of 30 Rock, another current comedy. But Big Bang Theory is much more hard core. However Big Bang Theory is, I think, not the cultural benchmark that The Breakfast Club was.

Edit: just thinking further, it occurs to me that Albert Einstein, with his dress and his hair, must have greatly informed the cultural stereotype of the badly dressed genius. Doctor Who is I think a sometimes "cool" version of Einstein. I think there's some overlap between the absentminded professor (as in flubber), the nutty professor (as in Jerry Lewis), Dick Van Dyke of Chitty Chitty Bang Bang, and the nerd. We have the high intelligence, the being lost in one's interests, the social awkwardness and obliviousness, and so on. Shared among the absentminded professor types (informed, whether justly or unjustly I don't know, by the common idea of Einstein) and also the nerds.
