Many a student bases most of their essays upon it and all arguments are settled by it. Wikipedia is the fountain of all knowledge.
What I love wikipedia for is its gloriously random lists(also the 5 clicks to Jesus game)
|Not this Jesus.|
The two lists that are well and truly the best I feel are the list of people who have claimed to be Jesus and the list of people who have disappeared mysteriously.
Both of these lists are a must read for all procastinators.
