Kevin Hart Can’t Keep Up With His Rich Friends

File this in the "Why Wasn't I There?" section.  Two of comedy's biggest names shared the stage early Tuesday morning in an impromptu performance at New York City's Comedy Cellar.  Throughout the week the two have performed separately at the Cellar, trying out new material; Rock because he's preparing for an new standup special, and Chappelle because…well, who knows, just be thankful he's still doing standup.  After performing solo for about 45 minutes, Dave Chappelle was joined by Chris Rock who took the stage to tell the audience, "Aw, you lucky motherf*ckers."
