Well... I've seen both of the last two Prime Ministers of my country - Helen Clark and Jenny Shipley - when they visited my high school and university, respectively. I once chatted with Prof David Bellamy (famous botanist and environmentalist) during a visit to the wildlife sanctuary on Mokoia Island, back in 1996. The trip almost didn't go ahead - his flight was delayed by a volcanic eruption, of all things - but he got through in the end, so I was able to meet a scientist I'd respected since childhood. Lastly, Jonah Lomu (former rugby player) came to my high school a couple of times, before he dropped out of the game due to illness.

Aside from those four... there've probably been a few, but I don't recall right now.

But earlier this year, I saw people who looked just like Willie Nelson and Viggo Mortensen. Only they weren't the real thing - Willie was an English tourist, and Viggo was a central European-accented guy on the bus.
