Anyone paying attention a week ago knew that Al Roker said the new mayor of New York, Bill de Blasio, knew nothing about weather (or snow days for schools), and the mayor got mad. It was one ridiculous tempest in a teapot. But we may get to relive it all again Monday when "Today" — working to keep that post-Olympics mojo on track — has Bill de Blasio on the show. No word weather .?.?. um, whether Al Roker will do the interview, but we kinda doubt it. Nevertheless, we will watch.
