Put a few million people on a tiny speck of rock in the middle of a whole lot of other people and strange things happen. I'm talking about Manhattan, of course. Ironic Sans: The Astoria Notes actually deals with, der, Astoria, Queens, but that is a whole 'nother speck of rock, just a larger speck than the speck I'm currently living on. If you've ever had issues with neighbors, even if they weren't necessarily horrible The Burbs types of encounters, you'll want to read Ironic Sans' bizarre tale about being told, by his neighbor, that she was pretty much following every move he made in his domicile, sometimes complaining, and sometimes twisting his habits into her own roommate eviction device. Enjoy.
