With one jokey insult told on a late-night TV show, Robin Williams has set off an international war of words between Australia and ... Alabama? Speaking on 'The Late Show With David Letterman' on Tuesday, Williams zinged that the people down under are "basically English rednecks."

The comment didn't sit well with Australia's leader, Prime Minister Kevin Rudd, who told a radio show: "I think Robin Williams should go and spend a bit of time in Alabama before he frames comments about anyone being particularly redneck."
