It's so sad. We were such fans that lines from his routines are part of our family lingo. We still use lines from his great album, "To My Brother Russell, Who I Slept With." For instance, if someone does something like drop a glass of milk on the kitchen floor, and we all come to look, the person who dropped it will look up and say, "The man came in."
My father did great impressions of Cosby and watching re-runs of the show was one of his old age pleasures. I'm glad he didn't live long enough to see his hero fall.
