Comedian/theoretical astrophysicist Louis C.K. (via)

Louis C.K. is undoubtedly one of the best things that ever happened to Twitter. It's not that he's constantly tweeting out really funny jokes about today's headlines. He's not that at all. In fact, he's actually pretty inconsistent, sometimes going weeks without a single tweet and then finally dropping an apologetic message like, "I seriously just can't think of anything to tweet. #sorry." But then, every once in a while, magic happens. he gets drunk on a plane or frustrated with his kids' homework, and then he's off on a several-hour, poorly punctuated tear.
