In March 2010, Louis CK hosted a tribute to George Carlin for the New York Public Library where he ruminated on comedy, having a career, and what makes for a truly great stand-up. The footage wasn't uploaded to YouTube until September of 2011, though, and since its release fans have been making some great things with it.
YouTuber JayPivot, in particular, has taken the talk and interspersed it with footage from throughout Louis' career to make a truly awesome video timeline.
So if you only know Louis from "Louie" or his stand-up specials, you're in for a treat, because there's some truly vintage clips in this tribute.
