If you like funny, you like Louis CK. I'm not sure there's a funnier guy out there right now.
I've been a big fan of his for a while. Heck, I even enjoyed his very short lived HBO sitcom Lucky Louie. From the "better late than never" pile, I finally saw his 2007 HBO comedy special "Louis C.K.: Shameless". And yes, it was funny, but you already know that.
He opened with a little bit "Tell Your Girlfriend I Said Thanks". NSFW!
