MadLibs: World's Greatest Word Game

I discovered I'm still juvenile enough to hysterically giggle over MadLibs creations. You know ... where you fill in words based on the a type (adjective, noun, a number, etc.) ... and then read the story with those words filled in once you've chosen all the words? You can even find quite a few site(s) to create your own stories on the web. Is there a cult of MadLibbers out there? Wanna play?
