"I could announce one morning that the world was going to blow up in three hours and people would be calling in about my hair!"

This quote by Katie Couric is a funny method of revealing how individuals can be more worried with unimportant matters than with more crucial concerns. She is suggesting that even if she were to announce a catastrophic occasion, such as the world ending in three hours, people would still be more worried with her hair. This quote is a commentary on how people can be so focused on the shallow elements of life that they can ignore the more important matters. It is a suggestion to be conscious of the larger picture and to not get too captured up in the little details.
