"There are three social classes in America: upper middle class, middle class, and lower middle class." -- Judith Martin
I had asked my pro (the one who was coached by Corky) and he had guessed "no older than 50." It's really kind of sad.
I would guess someone like Dorothy (or Peggy?) might get Corky, or they might get Tony. Then again, if the producers thought she really had a chance to go all the way and wasn't physically too frail/injured, they'd put her with Derek.
