Where do I know that name from? You've seen him retweeted on Twitter, probably at least 50 times today. Because he's funny. He's a funny, funny guy.

He's a comedian? Yes, a really funny one. Who talks wisely about politics, depression, addiction and nipples in the same breath.

How did he get so good at Twitter? "I'm pretty meticulous about trying to make every tweet entertaining or at least informative," he says. "Unlike some people who will tweet things like: 'Ugh, not having a great day. May get coffee in a bit.' How awful those people are. Many of them are named Seth."

And what's it taught him? He says Twitter's taught him how to be a better comedian. "If there's not an ease or at least a comfort in the way you've combined your facts, moods and whatnot," he says, "it will show and your joke will suck. It's also taught me to 'go for it' in that if I'm wondering: 'Should I say that?' I really probably should."

Give me an example of his Twitter LOLs. "The story of the Titanic speaks to me because I once tripped over a bag of ice at a party & then killed over 1,500 people."
