Ask yourself these questions:
- Do you know anybody from Bielefeld?
- Have you ever been to Bielefeld?
- Do you know anybody who has ever been to Bielefeld?
No? See . . . doesn't exist. A whole town just made up.
Well the simple version; it's a running gag that originated on a German usenet some twenty years ago and has been furthered even by a German chancellor and the town itself.
I love this 'simple' act of humor, one that took a decade and thousands of people to pull off, but it seems its a well-known thing in Germany even to the point that people form there will tell others they 'from some place in the woods'.
I should start something like that for my town . . .
