You're Nothing Without Your Phlebotinum: Batman is captured by Ra's al-Ghul and his henchmen, and is stripped of his utility belt (and, oddly enough, his shirt), two henchmen are assigned to lead him off to a cell, one commenting "not so tough without your precious belt". Both henchman are rendered unconscious by Batman roughly 30 seconds later, as the hero escapes and goes on to thwart Ra's scheme perfectly competently, even sans utility belt (but with help from Talia).
