The Case of the Two Doctors

A few weeks ago the Google listing changed for some PhDs. Now when googling searching for Brent Waters or Kevin Fu via Google, odd text appears as the first hit. The text consists of the title "dr" followed by the name, all in lowercase. The text itself does not appear on the target Web page.

An inside joke at Google? A cute bug? Google snuck into each thesis defense of yore? Or maybe abhi shelat is taking over the world, letter by letter all in lowercase.
