When did Louis C.K. get a personality? Is it the beard?

Reminds me of the old joke.

“Hey, Louis CK, what happened to you? You look completely different!”
“I’m not Louis CK.”
“You used to be young and thin, now you’re old and fat.”
“I’m not Louis CK.”
“You used to have hair, now you’re bald.”
“I’m not Louis CK.”
“You used to tell absurdist jokes, now you tell jokes about your life and family.”
“I’m not Louie CK.”
“You used to be light-hearted, now you’re bleak and existential.”
“I’m not Louie CK.”
“Wow, you changed your name too!”

And judging by the video Swords to Plowshares posted (great video, too), his balls.
