Congregation of David Smiths... weird.
I did have one reasonably odd name experience, though. I have a reasonably common name (though my "Marc" is far less common than "Mark"), but I've only run into a handful of other Marks in life, and never another Marc (never met anyone with the same full name, though Google tells me there are many). Through my 5 years as a college student, only ran into one other Mark in any classes...
...except for one late-evening hardcore geek class: wasn't worth useful credit for any major, and was basically just looking at cool stuff from the history of computing. Not a person in there wasn't a serious geek. And there were not only TWO other Marks, but another Marc as well. That was just creepy. Almost enough to make you believe all that name crap.
Uh, oh--I made two of the top three hits in Google for my first-last name. There went my anoymity.
