"You Got Peanut Butter On My Chocolate!"

I watch this from time to time. On paper, this had to have looked like a train wreck. Even now, I'm not sure it is not a train wreck, but I love it.

Do you think Pavarotti and J.B. were the first choices of the show's producers? Do you think maybe Question Mark and Itzhak Perlman were considered at first? Or Rose Marie and The Roots?
