I was laghing my ass off reading about the porn finds in your link!
I once found a bag of porn magazines in a bag on the side of an (industrial) road
when I was a teenager. You know you're poor when your first thought is "I can
get money for these!"
Selling them proved to be a little more work than I
initially thought but I did get a few bucks for them.
The tricky part was moving them without my parents noticing. I figured
out an idea though. I go to a friend's house and tell him I got some really neat
"computer magazines", once we get upstairs out of his parents earshot I tell
them they aren't actually computer magazines and ask him to hold them for
me a few days. Then I pick them up from him the night my parents are
bowling, put them in my school bag under the textbooks, and take them to
school with me the next day to put in my locker until I can sell them.
Eventually sold them to others at school, although some of the local comic
book shops dealt in used porn magazines none of them were interested in
them. One place said they were too new, annother said they were too old.
One guy I asked said he had some he wanted to sell so I ended up selling
his on consignment. (I learned from comic book trading "never get stuck
with excess inventory" so I wouldn't buy them outright.)
