But the one story about him that my wife told me -- back in the CPO Sharky days, my FIL thought Rickles was the funniest man on TV. So she and her two sisters (teens then), chipped in and bought two tickets to see Rickles at Atlantic City for their father's birthday.... He was never so disgusted in his life. He had no idea what Rickles was like live. I've heard he can be a bit overwhelming if you're not prepared for that sort of thing.
Back in the early 70’s, a buddy of mine thought Rickles was the best thing since ice cream. Went to see him ‘live’. His reaction was much the same as that of your FIL.
