Ha, when I was a kid there was a criminal in my city named Nguyen Thanh (I think he might have been on the run or wanted for a warrant or something). One day I was playing an online game and saw somebody who had "nguyenthanh" as their username. I freaked out and ran to my dad, excited to tell him that I'd cracked the case. Much to my dismay he explained to me that those were 2 of the most common names in Vietnam.
