I change my AIM icon fairly regularly, since I discovered iChat's wonderful applet for sizing/cropping buddy icons. After I rotated through all my personal photos I decided to check the web for some new ones.
I searched Google Images for my last name and picked out the best photo I could find, regardless of whether or not it was me. Since then, everyone has been asking me who my buddy icon was (some guy named Dan Haughey's 1982 picture -- how could you not use it with a moustache like that?), and after explaining it so many times I figured I might as well post about it here. So go forth chatters, and find the gems within your surname.
update: holy crap, I found the same guy's current page (and photo)
