We had a pretty epic one about someone posting about a very, very suspicious white car going around the neighborhood at 3:30 am, pulling up to houses, etc. A long list of comments about how everything is going to hell, things aren't like they used to be, this is why you should buy a gun, blaming the local officials and political party, etc. Finally, a post:
Hi Tom, that white car is mine. I have delivered your newspaper every day for the last 5 years with it.
