What makes 'cos' unique?

Note: the category and title are both clues and you may need to use some twisted logic as the answer is not straightforward

Cos is unique for two very good reasons: first, his concern and interest in the welfare of kids in very praiseworthy; and second, his television show "The Cosby Show", broke many racial barriers and stereotypes. So Bill Cosby (aka Cos) is one of the few truly unique performers.
