Louis CK Makes 'Late Show' History, Says Bye To Letterman In Best Way Ever

Who would have thought that the man who introduced us to the phrase "bag of dicks" would be the one to perfectly sum up our feelings about David Letterman's impending retirement.

It's hard to believe, but that's exactly what Louis C.K. did when he stopped by "Late Show" this week, making history in the process.

Season 4 of "Louie" premieres Monday, May 5, at 10:00 p.m. ET on FX.
