I have an odd fascination with the Prime Ministers of Australia. From Gough Whitlam, the only officeholder to be dismissed by the representative of the British (and, I suppose, Australian) crown, to Paul Keating, who proved that being super foulmouthed is not enough to guarantee your reelection on Prison Island, there are any number of fairly interesting stories. But it's tough to top that of Harold Holt, the man who went for a swim and never came back.
