Robin Williams joins UCB house improv team for a night

Famous actors and comedians drop in at the Upright Citizens Brigade theaters in New York City and Los Angeles all of the time. Particularly for ASSSSCAT. What makes the Robin Williams appearance last night at the UCBT in NYC so surprising is that he merely wanted to play along with an improv troupe. Any improv troupe. The lucky team? Bangs. So how'd it go? Read brief interviews with improvisers from last night's Harold Night in NYMag's Vulture blog or The Apiary, or Tumblr along with Bangs member Craig Rowin.
