That's the joke
Many years ago, NBC News sent Buddhist Monks out into the Middle West to scour the Anchorman farms to look for the Annointed One to succeed Tom Brokaw. The requirements of the Annointed One were that he must look like the most WASPy human being on the planet, have hair that would stary perfectly in place in a Mach 2 wind tunnel, and be so bland that even Bloodhounds couldn't detect a body scent. When Brian Williams was found, they hermetically sealed him off in a vaccuum bag to be opened only when ready to succeed Tom Brokaw. In celebration of the completion of their sacred task, the Buddhist Monks made a Mandalay Sand Painting in the design of a Happy Face and then dined on a feast of white bread and mayonaisse sandwiches.
