Chappelle showed up first right before the end of the last show and went up onstage. Chris Rock showed up shortly after and stood in the back watching his set. Neither knew either were going to be there. Chris surprised Dave by walking onstage and the two did an amazing show together. At one point during the show Chris Rock went through his phone and texted Jay-Z and then tried phoning Lenny Kravitz and Arsenio Hall from onstage. Marlon Wayans showed up for the last 30 min of their set. I've seen the two comedians do sets back to back at the Cellar before but never together. It was one for the books. Great night.
