I found Peter's Ruler Of The World web page which had a link that took me to the point of this thread:
The Pete Collective
In 2004 some friends bet that I couldn't get a bunch of other people called Peter to meet up with me at the same time in the same place. Inspired by the challenge and discovering that there have been gatherings of Marias in Spain and Mohammeds in Dubai, I decided to up the stakes & go for the world record. I set up this website to entrap my namesakes and get them to pledge allegiance to meet me on 10th June 2006 in London & 'Give Pete a chance'. I need 2000 Pete's on board, to meet me in one place, at the same time. What could be simpler.
Now, my name is not Peter, so I'm not going. Anyone here planning on attending?
