>After 33 years, the wise if supremely peevish Andy Rooney retired his CBS 60 Minutes commentary spot Oct. 2. Over the years he whined and opined about everything from the nuisance of cotton wadding in pill bottles to the bother of having to live in the same era as Lady Gaga. He could have been David Letterman’s cranky uncle. Now 92, he signed off by expressing gratitude for his career. And asking viewers not to bug him in public.
