These comments are an appreciation of Harold J. Stone, who plays the loan shark in this episode. There was something about his acting that just radiated credibility. He was a bear of a man who could command the screen. What I recall are the flashing eyes and the steely voice. It would take a confident actor opposite him not to back down from that. But Stone could turn that stereotype to humor and self-parody very nicely.
The Jerry Lewis tribute to Harold J. Stone (the full name seems somehow appropriate) reflects the respect Stone likely commanded in the business of Hollywood. I grew up seeing him in many supporting roles, never knowing exactly who he was.
What he was, was one grinder of an actor. Take a look at his filmography year-by-year. If the man wasn't working some lines, he must have been miserable.
One of the early pro's of TV who is missed.
