Source of all Evil?

I noticed this when I did a search on Google using the keyword Dynamics NAV or Dynamics GP (or AX or SL, or whatever).

http://thesource.ofallevil.com/dynamics … rview.aspx

It seems random, on top search results it displays www.microsoft.com. On the later pages, it displays thesource.ofallevil.com.

The source of all evil? Is this a Microsoft joke? Or did Google intentionally do this?
