Yeah, that was season one, the fancy dress party where Penny's caveman ex-boyfriend turns up dressed as a caveman. Have to give them points for subtlety there.
Yeah, he even puts his beer down on the counter before leaving with her to go get coffee. This week, we should find out what happens once the coffee wears off the effects of the buzz. Maybe he'll realize he doesn't need the alcohol.
They're usually pretty careful to establish that Raj has imbibed some form of alcohol prior to talking to a woman.
I guess I'm in the middle on this "does TBBT get nerd culture right?" question. It depends on what you're talking about. The writers frequently don't seem to get it on aspects of SF fandom. If that's what you mean by nerd culture, then yeah, I agree that it's often written from the point of view of a mainstream person's outside view of nerd culture. But if you're talking about the portrayal of physics academia, then it's often been scarily spot on, at least in the early seasons. As someone in astronomy/physics academia, I thought some of the discussions in Season 1 about teleportation or jokes about string theory and the like were great. As late as Season 3, there was still some good stuff in that regard, though it was less frequent. Raj and Sheldon working on dark matter research by staring at the white board for hours was hilarious. But in the more recent seasons, their jobs at the university are just not much of a focus anymore. The show's much more fixated on the relationships between the characters first and foremost, with their geeky SF fandom second, and their jobs as physicists a distant third. EDIT: Should also add: Everyone I know under 40 years of age within physics or astronomy academia who has sampled the show in its early seasons enjoyed it, at least a little. Never met an actual physicist who found it insulting.
It was often said (and proven) that the math/physics stuff they have on their boards are actual scientifically correct.. i can't understand it as it's way beyond my math and physics knowledge so i'll take it at face value. However i do miss the more science oriented jokes sometimes.. it's what made the show unique and if you were persistent enough you might even check a topic where you didn't quite understand the joke and learn something (yeah i know.. actual work without being forced to do it just for the fun of it! ).
I pretty much agree with all that you've said. As I mentioned earlier, I feel that the "science nerd" aspect is pretty accurate. The "scifi nerd" references used to be more obscure but have always tended to be those more understood by the mainstream. This doesn't bother me so much though, because why should anyone choose to make a show where 85% of the audience has no clue what the characters are referencing or why it's supposed be funny? Sure, it would be hilarious to those of us engaged regularly with that culture, but to direct the show only towards us would be pretty limiting. Anyway, I also agree that the science jokes, while accurate, have died down in the past few seasons to focus on the relationship dramas, and I do wish they would go back to that sort of humor more often.
