John Mulaney is a name a lot of people dont know, but if you want to seem "hip" and "ahead of the game" (as the kids say these days), learn it now because he's going to make it big very soon.
He's already a writer on SNL and had his first stand-up at Comedy Central. Rumor has it he'll become a new on-screen cast member on SNL for this upcoming season too. I saw him live in NYC a few years ago and he had the place rolling.
Here's a few snippets from his CD (some NSFW)
