Last night, popular hipster comedian Robin Williams turned up unannounced at New York's Upright Citizens Brigade's typically student-attended Harold Night to perform with the Bangs team (price of admission: $5). According to UCB's Charlie Todd, Williams played an out-of-work Sean Connery auditioning at a casting call for Hugh Jackman types, and an underage drinker trying to sneak past a bar's bouncer by hiding in his friend's hoodie. "He really rose to the moment," says Todd. "It was surreal to see him with his head under my friend's shirt."
