Last night was penultimate episode of this season and the last episode of the three-episode "Late Show" arc. Very good episode and I felt for Louis' struggles through it. Despite how gruff Jack was being towards him it seemed Louis did get "something" from it. And like his buddy at the end said, he may not have gotten the show but he was
good enough to take money out of Letterman's pocket.
The faux show Louis had was good too and I'd be interested to see an actual show like that for Louis C.K. (though I doubt it'd ever happen.) Loved his interview with Susan Sarandon where he admits that she was his "first time."
