Far too interesting Wikipedia Pages (by category)

Warning: This post could lead to a serious waste of time (source).

Dude,

Just to kill your productivity today, over the past few weeks I've been bookmarking Wikipedia pages I have found far too interesting. This says something. I'm not sure if it says something about Wikipedia, my browsing habits, or if it explains how Google knows I'm a male in my 30's, but none the less I felt it was worth sharing with you... and I guess the world.

Also I organized them into arbitrary categories to kill my productivity for the day. We're even.

Criteria
Of course this all varies from user to user. My criteria for considering Wikipedia pages to be too interesting is if they meet one of the following:

Interesting
There are a number of things in the universe that are just plain interesting. These will prepare you for that cocktail party you've always been afraid of not having anything to talk about at.
Example: http://en.wikipedia.org/wiki/Geology_of_the_Moon

Unknown Before
Something that was completely unknown before found on Wikipedia. Most links fall in this category because there is a lot I don't know. Bonus points if it is related to a topic I already know about.
Example: http://en.wikipedia.org/wiki/Punctuation_(chess)

Basically Hidden
Something incredibly basic that has a surprising amount of interesting information. A little harder to find because you have to read (or at least scroll) most of the article.
Example: http://en.wikipedia.org/wiki/Solid

Surprising List
A list that when you first see it you wonder why it exist in the first place, but as you read it you wonder why you’ve never heard of this list before.
Example: http://en.wikipedia.org/wiki/List_of_music_considered_the_worst
