Back at the ACME Comedy Theatre for the second year in a row, PCAT pulled out all the stops in 2011 with an incredible lineup of guests that included Amy Poehler, Jon Hamm, Andy Richter, Lisa Loeb and the unscheduled Adam Carolla, who happened to be eating dinner next door and dropped in to tell stories of his days as an improv student (and in-house carpenter) at ACME.
