Though I've never heard of Karl Malden, I'd say it still counts. I'm a bit saddened about Mrs. Slocombe, though to be honest, I didn't necessarily know she was still alive. I really enjoy Are You Being Served, and even a bit more the few episodes PBS showed probably almost a year ago of Are You Being Served Again.
However, if they were 6 and 7, who was 5? I know McMahon, Jackson, Fawcett, and Mays. Who'd I miss?
