The people who dress up as Santa Claus usually are sweating indoors, because that suit is made for winter wear, outdoors. Saying it that way does get me past the first challenge. Not everyone dressed in the red suit can be the real Santa Claus and every parent has to explain why there are so many people dressed up that way. So, to begin our show about "The Guy in the Red Suit", we have to make it clear that many people dress that way to remind of us of the legend of Santa Claus.
Every year the legend grows. Have you noticed that? And no matter how many people have tried to tell the story, each telling has more details to explain. This is clearly a legend that is active in the imagination of every generation, which makes the character get bigger and better.
