Louis C.K. came on Conan to promote his FX show Louie. (btw it's a hilarioos show you should all be watching it!)
So, in his stand up Louie talks a bunch bout being a single father, BUT in this interview with Conan O'Brien C.K. says there is something much harder than raising kids: raising a dog!
He says he saved his dog's life and now she hates him for it!! LOL!
