conan shaved?

So I think I saw part of a new episode recently where Conan was clean shaven. I can't really stay up late enough to watch the show regularly like I used to and I was bummed that I missed the first show without the beard. Why did he shave before the strike ended? Does anybody know where I could see a clip of the show where he explains this or if not, could anyone just fill me in on what he said about it?
If I'm confused and it wasn't a new episode that I saw then please disregard this. :)
