A Brief History of Streaking

From Der Spiegel:

This scene marked a world first: 25-year-old Australian Michael O'Brian is believed to have been the first person to "streak" the audience at a major stadium. During a 1974 rugby match in London between England and Wales, O'Brian ran onto the playing field naked. The photo of his arrest illustrates the forbidden appeal that comes with streaking. Every streaker knows that it's the easiest way to instantly please tens of thousands of people, and even the authorities have trouble concealing their delight when streakers strike.

The photo gallery is hillarious. There is, of course, nudity, but it's all tastefully done ... some of it , at least.
