because peoples' impression that plotz is elitist, condescending, and full of himself really gets to them? i, however, know that their impressions are wrong, as i have a lot of experience in dealing with this particular subject. additionally, although we'd like to think it's always plotz and the same 2 people going back-and-forth, it really seems to be plotz going back-and-forth with a nonstop rotation of any number of people. hence his nickname, the "Energizer Dummie."
