pretty sure one of my first was "porn"
i remember going to the public library with friends, downloading a bunch of pictures to a 3 1/2" floppy when none of us actually had internets, then selling copies of the disks at school.

I was mad hustling porn when I was like 13. Mags, disks, tapes, you name it. Me and a buddy where the town porn kings back in the day. If you could save up $20, we could hook you up. Then we branched out into hustling xmas chocolates door to door and got busted...
