I heard a clip of Ernest Borgnine today, where he talked about having recently met some fairly young people (under 20, I think), and they didn't recognize him by face or by name. He asked if they'd ever heard of McHale's Navy or the movie "Marty" or a few others, and they all said they had not.   Then he asked, "How about Sponge Bob Square Pants?"   They grinned and said oh, yes, for sure.   When he told them he was the voice of Mermaid Man, they were all excited and wanted his autograph, etc.   

Glad he lived a nice long life and gave us so much in the way of good entertainment.
