Why don't CarolC and The Banjoest just do a Google search and find out the facts before making things up?

I never said the character was played by Greg Morris.

But I was wrong about the Andy Griffith show being the first to have a black character. Aparently there were a limited number of shows that had black characters who were typical of the prevailing US stereotypes of black people at that time.

However, not too long ago I saw a show that was a retrospective about the Andy Griffith Show on which I'm pretty sure I remember it being shown that there was a black character on at least one episode (and I guess they felt it was groundbreaking because the character wasn't a stereotype). It's possible that my memory is faulty about this. I don't have any problem with being wrong. But I don't think you can prove me wrong just by doing the kind of search you did in this case.
