Knuckles, Vinnie and Kowalski were three thugs employed by the Joker.
Joker hired the services of Knuckles, Vinnie, and Kowalski when he sought revenge on the Laff-Off competition. He introduced them as the new judges after he had successfully disposed of the old ones. Though the three easily managed to subdue Laff-Off's host, they didn't have a chance against Batman and Robin, who landed right on top of the three goons, knocking them out.
