This is a kind of typical dialogue from an episode:

    Sheldon: Leonard, where do you stand on the anthropic principle?
    Leonard: Interesting question. On the one hand, I always thought…
    Sheldon: You don’t even know what it is, do you? The anthropic principle     states that if we wish to explain why our universe exists the way it does, the     answer is that it must have qualities that allow intelligent creatures to arise     who are capable of asking the question. As I am doing so eloquently right now.
    Leonard: I know what the anthropic principle is.
    Sheldon: Of course. I just explained it to you. Now, where do you stand on     it?
    Leonard: Where do you stand on it?
    Sheldon: Strongly pro.
    Leonard: Then I believe that God created the world in six days, and on the     seventh he made you to annoy me.
    Raj: Hey, guys.
    Leonard: Hey.
    Sheldon: Yeah, wait, Raj, where do you stand on the anthropic principle?
    Raj: I’m all for it.
    Sheldon: Attaboy!
    Leonard: Well, hang on. Why do you believe that he knows what it is and I don’t?
    Sheldon: Oh, Leonard. Let’s not take a saw to the branch we’re sitting on, shall we?

Why is Sheldon such a douchebag? He is socially incompetent but does he have to be an asshole too? Why doesn't Leonard or anyone else ever want to discuss science with Sheldon when it's supposed to be their biggest interest? It's like they are ashamed of being smart people.
