Knuckles, Vinnie and Kowalski were three thugs employed by the Joker.
History[]
Joker hired the services of Knuckles, Vinnie and Kowalski. They helped him during his plot to steal an atomic bomb[1] and later during Joker's 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. Swinging into the comedy club, the Dynamic Duo landed right on top of the three goons, knocking them out.
