 The Driscoll brothers were the local gangsters with a fearsome reputation for violence (although in order to avoid serious problems with the police, they followed a strict rule in never harming the victim's head).They beat up Del Boy after he failed to repay money owed to them, and in the same episode left Mickey Pearce and Jevon with broken bones for a similar reason.In a similar joke to the different-looking Del and Rodney being brothers, the Driscoll brothers also differ in height, but by a good , though in their case the taller brother has the brains.
