Funny Farm - Web-based puzzle

This one is seriously hurting my head. Funny Farm is a web-based puzzle game that's been making the rounds recently. It's kind of a big game of word association. You start out on a mostly blank board that has one box labeled "On the farm" and a few blank boxes connected to it. The blank boxes conceal words that are related to the words connected to it, and guessing a word reveals it and more connected boxes. In this way, you fill out an ever-growing network of words. Some will give you access to other parts of the map, until you get to the far corners of the map, which give you clues to a larger riddle. Funny Farm will completely boggle your mind, and is at once extremely frustrating and very rewarding. It also has a handy collaboration feature whereby if you click on "Save game," it will give you a URL that contains your progress (encrypted, of course), and you can share the URL with your friends, whereupon all of the words you have uncovered will be merged with their game. I highly recommend teaming up with your friends if you want to solve Funny Farm in its entirety.
