I couldn't think of an answer when I first saw the message, but, moments ago, I decided to reply:

Nothin. Just sitting here at my cousin's desk, chewing gum, wearing a bathrobe that he stole from a fancy hotel in Beijing, thinking about nonprofit web applications, looking at a picture of my sis and my granny, noticing that there's a box of fake mustaches a few inches to my left, just in case.

And the best part is that that's only a tiny slice of the real answer.
