Andy knew who they were when he hired her. What is happening is beyond his greatest dream. He wants the publicity to boost the ratings.
The only reason that caller got through to ask Nancy the question on his WWHL show was because Andy okayed the question. The questions are vetted long before the show. Have you tried to get through? Where do you find the telephone number? Where do you go to post the emails? Hard to find isn't it? Maybe the callers are plants.
The question, Nancy's response and Andy's little "of my gosh" act were done to bring up the ratings.
