Kenneth Fitzgerald

The guy that Howard knew that could get the liquid helium that was in short supply need by Sheldon and Leonard for an experiment. His name was Kenneth Fitzgerald and though he talk tough, he was intelligent and able to discuss their superfluid theory and debate the meaning of English expressions like stalemate and Mexican standoff. When the guys no longer wanted the helium he was willign to take it off their hands for a price. He also knew of guys who could take care of the Swedes that were trying to take the credit for the superfuild theory for a price. Eventually Ken ends up back at Sheldon' apartment still debating the meaning of words, drinking their beer and watching "Ernst Goes to Jail." That movie scared Sheldon straight and he hopes it will do the same for Ken who is willing to change.
