Me: It must be a special kind of geek to really laugh your butt off when reading a British book about punctuation.
Adam: No, you're a dork.
Me: (indignant) No! It's a geek thing! A nerd, really. I mean, you have to be smart in order to even get the jokes. Like those science jokes. They're science nerds. There are book 'n language nerds.
Adam: Getting the jokes makes you a nerd. Laughing at them makes you a dork.
