Sometimes the mac shows a tiny american flag in the menubar. This bothers me. I don't want to think about the United States of America and all the issues surrounding the american flag every time I check the time in the menubar. I certainly don't want to program myself with the jingoism that (these days) images of the flag connote.
The way to turn this off is to go to the International preference pane and uncheck "Show input menu in menubar."
