I used to jokingly prank people that Delaware doesnt exist, it was just a big building full of drawers and offices for Corporations. I asked- have you ever been there? Do you know anyone from there? One person claimed to have driven thru there, but I pointed out that road signs are easily faked.
We even, long afterwards had a SDMB thread about it, and there was a Tumblr page on it, all starting after my pranks in the 1980s. Of course, that doesnt mean the jokes originated from me, it is a peculiar state.
