Batman Vol.1 #679
The Batman of Zur-En-Arrh bursts into a tailor's shop where Le Bossu is getting his henchmen's costumes made. Shaking down the tailor, he goes to a roof with gargoyles and ponders the situation while Bat-Might chats to him. When the gargoyles start talking to him, referring to "the grid", he remarks that the area around Crime Alley is "a machine designed to make Batman". Suddenly a group of Le Bossu's henchmen come looking for him, and he realizes that a tracking device has been hidden in one of his teeth. Distracting their sensors by tying the offending tooth to a passing pigeon, he ambushes the men.
