what goes on in those brains of theirs

Artists! They really are as odd as everyone thinks they are. From an article on Miyazaki:

Although much of Japan's kid-oriented anime has been exported to the U.S., a great deal more — such as "Anpanman," a hugely popular series about a bean-paste-stuffed bread roll — has not. (A fan Web site notes, "To a non-Japanese person, the concept of a living bread superman who fights giant germs and feeds the hungry with pieces of his head may seem bizarre.")

And from a recent book on Leonardo:

There was a monk on hand to make notes as he painted "The Last Supper," in Milan, recording with wonder that Leonardo would sometimes show up, stare at his own painting, and then walk away again, finished for the day.

These are my brothers.
