Six Degrees of Wikipedia

Six Degrees of Wikipedia is, from what I can tell, inspired by the 6 degrees of Kevin Bacon game. The site will let you insert any two words and then determine how many clicks and what articles you have to go through to get from one to another. My favorite example is that to reach the article "giggles," from the "shit" article, you have to pass through the Canterbury Tales. Coincidence? I think not, good sirs. Also the site has some pretty cool information how the geographic center of Wikipedia in the terms of what article takes the fewest clicks to get to every other Wikipedia article
