What's your favorite Wikipedia page and why?

Personally, I like to check the South Park Controversies Page every now and then.

The page on Quantum Entanglement is fascinating and has so many rabbit hole links that lead to other rabbit holes themselves. I still go back and re-read them here and there to improve my understanding and check for laymen's updates without all pop-science nonsense you encounter elsewhere.

I'll come back and post a few more when I can think of them!
