From Tigerhawk, who calls it Six Degrees of Hitler
Here is the task set before you:
1) Go to Wikipedia.
2) Click any random link on there.
3) You have five clicks to reach Hitler's article.
Varying levels of difficulty.
Easy Mode: Any links
Nightmare Mode: No Country Links
Hell Mode: No Country or Date links
My first tries, starting with my last wikipedia lookup:
Colin Renfrew, Proto-Indo-Europeans, Aryan Race, Adolph Hitler.
From today's wikipedia front page: Waitaha Penguin, Proceedings of the Royal Society, Human Biology, Freiherr von Blomberg, Adolph Hitler.
Have a go at it.
