What does it mean to be a successful comedian? How far can the boundaries of taste be pushed to get a laugh? Four top comics, Ricky Gervais, Louis C.K., Jerry Seinfeld and Chris Rock, discuss and debate their craft.

The Comedians of Comedy is an occasional stand-up comedy tour featuring Patton Oswalt, Zach Galifianakis, Brian Posehn and Maria Bamford that was documented in a 2005 film and 2005 Comedy Central television series of the same name, both directed by Michael Blieden.

2002 HBO Stand-up Special starring Robin Williams. Recorded and broadcast live from New York City's Broadway Theater at the culmination of his historic 2002 sold-out tour, this special finds the Oscar-winning actor/writer/comedian returning after 16 years to his stand-up roots to deliver what the Washington Post calls "...in its madcap way, a seminal cultural event."

Bad Grandpa .5 gives you a whole new perspective on the world of Irving Zisman with bonus scenes and pranks also featuring Spike Jonze as "Gloria" and Catherine Keener as Irving's wife "Ellie", plus a look at the evolution of Johnny Knoxville's naughty alter-ego, the makeup effects, and a behind-the-scenes peek at the idiocy it takes to make a hidden camera movie in public.

Stand-up comedian Kevin Hart talks about his family, travel and a year full of reckless behavior in front of a live sold-out crowd in London.
