No it's perfect. That way if you like some other show and are worried you'll be judged about it now you can think "well at least it isn't the Big Bang Theory"
I have never watched an episode and assumed I was in the right? But I know they made that funny meme where Charlie Sheen says. If it's important than you wouldn't have forgotten it, and that is a joke, which is a phenomenon I don't think I've ever heard of or seen from the big bang theory
