Taken from slashdot:

Some students at MIT wrote a program called SCIgen - An Automatic CS Paper Generator. From their website: SCIgen is a program that generates random Computer Science research papers, including graphs, figures, and citations. What's amazing is that one of their randomly generated paper was accepted to WMSCI 2005. Now they are accepting donation to fund their trip to the conference and give a randomly generated talk.

From the author's website:

One useful purpose for such a program is to auto-generate submissions to "fake" conferences; that is, conferences with no quality standards, which exist only to make money. A prime example, which you may recognize from spam in your inbox, is SCI/IIIS and its dozens of co-located conferences (for example, check out the gibberish on the WMSCI 2005 website). Using SCIgen to generate submissions for conferences like this gives us pleasure to no end. In fact, one of our papers was accepted to SCI 2005!
