c|net has the article Facebook pokes holes in Princeton research with parody. The article had a link to the Facebook article  in question, Debunking Princeton.

This trend suggests that Princeton will have only half its current enrollment by 2018, and by 2021 it will have no students at all, agreeing with the previous graph of scholarly scholarliness.

Facebook even gives you a chance to peer review the article.  For similar scholarly studies see the previous blog post by RichardH Diversion–Highway Fatalities and Lemons.

One of the comments on the Facebook article shows that the rate of murder declines with declining use of Internet Explorer.
