This weekend, Louis C.K. will host SNL for a second time. But his history with the sketch show dates back to 1997, when he co-wrote a Saturday TV Funhouse segment with Robert Smigel that distracted from the 1997-ness of host Helen Hunt and musical guest Hanson. C.K. has “contributed” over a dozen TV Funhouses since the 1990s, most recently in 2007 during the regrettable Zach Braff/Maroon 5 episode. It was almost a lot more: the founder of the Rescue Me Haters Club actually auditioned to be on SNL.
