I never come upon good stuff, but I'd take it if I could!
Our last house we remodeled, I could not believe the stuff people took, I'm talking NASTY stuff. The house had been trashed by renters so we gutted it, we had ceiling fans that were literally black from smoke, I would put this stuff in the trash and people would pick through the trash and take it. We had a pile of carpet we took out, it was covered in dog pee and stunk of smoke, someone knocked on our door one day and wanted it. We got rid of toilets that I think hadn't been cleaned since they were put in 15 years before, the same way.
I had two women get into a fight over an old dishwasher on the street. When we first bought the house, it is full of furniture still, not the good kind either, I drag two ok pieces outside, a guy stopped, asked if we had more, and then took everything single thing that was in the house, it took him four trips to do so. The best one was when we stuck out an old washing machine that leaked, I put a sign on it describing it's issues. Not even 2 minutes later a tractor picked it up.
Yes, a tractor. I think he was doing road work in the area, drove by, stopped, backed up, and loaded up the washer in his bucket, it was highly entertaining to watch.
