Why do post-apocalyptic people dress like morons?
One note before I open up this week's mailbag: As last week's "PA" revealed, I am not infallible. I don't know why you would think so, given that I'm a fictional fake postman. I know a lot of junk, but I think I know more than I do, so I rely on you attractive readers to "augment" my answers in the comments. The fake USPS thanks you for your help!
