This is the show where simply acknowledging a character owns/owned a NES was the entire punchline of a joke.
It did seem like the writers’ only concept of “geek/nerd” was superficially gleaned from only watching other shows and movies about geeks/nerds. Which created basically a show about some of the dumbest “smart” people I’ve ever seen.
I find it a lot more palatable if you assume it’s viewed from penny, as an unreliable narrator. There’s actually a lot more geeky stuff going on under the obvious, but she doesn’t notice it.
