Recently I've been spending a lot of time fooling around at the Uncyclopedia ( http://uncyclopedia.org/)
I suppose there are some who would say that I've been wasting my time, but I differ in as much as I believe that humor is an essential part of living a good life.
The Uncyclopedia is a wiki, founded as a spoof of Wikipedia, which is in my opinion one of the really great marvels of the Internet. If you're not familiar with it, I'd encourage you to use it and what's more participate. It seems a bit daunting at first, but once you get the hang of it, it's quite easy.
Surely you know something about some thing which is unique, or special, and you may also have some need to exercise your sense of humor which is just like any other ability we have: if you don't use it, you loose it.
Try them both, I'm sure you'll find it time well spent.
