The Wikipedia Game

Speaking about Wikipedia, here is a video clip about a game you can play with it.
You can skip the first 20-25 seconds where the girl jumps around and go straight to the explanation about the game.
Basically it's something like the six degrees of seperation (http://en.wikipedia.org/wiki/Six_degrees_of_separation) - your goal is to get from one random article to another using only internal links of Wikipedia. It will be interesting if this can be done by up to 6 steps (following the six degrees argument).
I haven't tried this before, but it does look addictive.
Best of luck.
