"Here's a good one. Helen Clark, former prime minister of New Zealand: her opponents have observed that in the event of a nuclear war, the two things that will emerge from the rubble are the cockroaches and Helen Clark. [Laughs]"
Setting Hillary's sense of humor aside for a moment (the joke doesn't get funnier if even you happen to know something about New Zealand politics) Helen Clark is the current prime minister of New Zealand.
The diplomatic ramifications of this become even more dire when you consider that New Zealanders have been skeptical about Hillary Clinton ever since she met Sir Edmund Hillary, the first mountaineer to climb Everest, and mentioned that she had been named after him. It was later pointed out that Sir Edmund climbed Mt Everest six years after Hillary Clinton was born.
