Gerry Lang spent a lot of time training. From his wikipedia page:
http://en.wikipedia.org/wiki/Gennaro_LangellaGennaro received the nickname "Gerry Lang" from Carmine Persico because of his conspiracy of "knowing karate." When travelling in some neighbouring states, he had to go to the police and inform them that he knew karate and that his hands, per say, were to be known as 'lethal weapons' when he was charged with assault and the judge asked him if it the attack was intentional or not.
