I'm thinking about printing a t-shirt on which it would say:

"If only you and dead people can read hex, then how much of a nerd are you?"

Or possibly:

"There are 10 kinds of people, those who are smart-asses and those who just don't care."

I'm not sure about the exact wording yet, but I'm pretty sure I'm not actually going to print any t-shirts, so that's alright then.
