My colleagues googled me and discovered someone with my name that they claim also looks exactly like me. I dispute this (not only because he's over 50 and American). But I'm still slightly disturbed.
Someone with my name draws Harry Potter fan art. Someone else is a pop star. And another one is head of a Meat Board (?) or something, if I remember correctly. But I'm the best one. :)
Whereas I (as could a great many people I suspect) can be fairly sure that my name is unique, even if we discount my middle name. Anybody with my surname is a member of my father's-side family and due to cultural/ethnic reasons, the probability of any of them sharing my first name is extremely low.
According to google, I have one phonetic namesake (ie her name is spelled wrong) who's a successful college runner in the US. Anyone who knows me will know she's not me as I'm crap at running, whereas I am rather brilliant at writing - she doesn't have any google-indexed articles published on the Institute of Biology's website.
