Here is a round-table discussion between comedians Jerry Seinfeld, Chris Rock, Louis CK, and Ricky Gervais on the subject of stand-up comedy. As with the clip of Ricky Jay’s 52 Assistants show, I’m not entirely certain about the legality of this upload to Youtube. With more than 4 millions views it’s not exactly run under the radar, but you never know, maybe the lawyers haven’t seen it yet.
On the off-chance that HBO has seen it and doesn’t care, then get to the video and watch it. It’s great. It really gives a lot of insight into what it takes to be a successful live performer. If by some chance the people involved decide that this being on Youtube isn’t kosher, try to find some way to watch it legitimately.
