Crazy Google subcategories

Today I typed “wikipedia” into Google. Look at the weird subcategories that showed up under the main wikipedia.org link:

What the?!?

So of course I clicked ‘em all. “Wikipedia:Hauptseite” and “Accueil” take you to the home pages of the German and French versions of Wikipedia, respectively. “Tirol” takes you to the German-language page describing Tirol, which is apparently “a historical region of Western Central Europe” (according to the corresponding English-language page). The last three links take you to the English-language pages for the movie Chitty Chitty Bang Bang, Denzel Washington, and commodity markets.
