|Knuckles, Vinnie and Kowalski|
|Notable members||Knuckles; Vinnie; Kowalski|
Knuckles, Vinnie and Kowalski were three thugs employed by the Joker.
Joker hired the services of Knuckles, Vinnie and Kowalski. They helped him during his plot to steal an atomic bomb 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.
