This plot is notable because it is the first time that anyone in the family has encountered an overtly racial problem of any kind. In fact, I'm almost positive that race has been explicitly mentioned only once before, when the parents and grandparents discussed their participation in the March on Washington. It says a great deal that in order for this cast to be viewed as accessible a white audience, they had to avoid ever saying "black."

Alright, that about does it. Now go find a publication that discusses racial politics on The Cosby Show and read what it has to say about this episode, because it's probably fascinating.
