When I was in the dorms my freshman year of college, the cable TV was wired serially from room to room.
So I put my favorite porn on the VCR, disconnected every room after ours from the normal cable feed, and connected them to my VCR. They only got channel 3, but at least the content was interesting.
After the furor in the hallways 10 minutes later I chickened out and put it back to normal.
