“I'm drunk, here we go!” shouts Patton Oswalt to kick off his third album. But the comic comes off as the sanest man in the room while riffing caustically on his grievances (Republicans, Cirque du Soleil, birthdays) and nerdy preoccupations (Star Wars, four-star chefs) throughout this surgically precise 2006 show in Austin, Texas. And when Oswalt mercilessly confronts a heckler during a carefully calibrated bit about birth control, the miscreant doesn't stand a chance.
