The exchanges are frustrating at times, Mr. Marx being so relentlessly, well, Groucho. But it's fun and sometimes illuminating to see this mythic figure on someone else's turf. (The answer to the title question, by the way is: No, it's damned sad.) GM: "I have said the things that no one else has dared to say." WFB: "Why? Why?" GM: "Because the audience loves it." WFB: "All right." GM: "If you have a general, like I had General Bradley on the quiz show--nice man, very nice man; might even conceivably be a good general--well, I kidded him all through the show and the audience loves that because they don't get a chance to do that to mayors or politicians or bank presidents..." WFB: "But it's very healthy, isn't it?" GM: "Yes, it is. There's not enough of it."
