If you look at the source code of this page, you'll be even more shocked: looks like it's simply a MS Word document saved as HTML, it's overly complicated and contains lots of "Mso*" classes. And no, it's not unstyled either, it's just that on computers that don't have Times New Roman installed, the browser falls back to the same serif font that is used for unstyled text (and if you have it installed, it's probably the default serif font or indistinguishable from it).
