Here's a game to play when you're bored:
Given a starting and an ending entry, try to link you way through wikipedia from the starting article to the ending article. You may only click on links within the article itself or under the "see also" section; you may not leave the website; you may not click back on your browser.
Example: Ball ==> War
ball - Columbus - Viking - reformation - invasion (goes to page "Ottoman wars in Europe") - Military of the Ottoman Empire - army - war
You'll be surprised how you can connect different completely unrelated things on wikipedia.
First person to post a sequence of links between the two gets to pick 2 more articles for someone else to link.
Here's one to start off: Shampoo ==> Post-it Note
(Here's a hint: you can get to Post-it Note from the "desk" article on wikipedia; only the link will not say "post-it")
