I remember a story many years ago of the divorced husband, before leaving the house, put dead ?fish? in the expensive curtain rods. The house smelled, nothing they did seemed to work, so they put it up for sale at a low amount.
The ex bought the house from them, then fixed the problem.
I heard a story many years ago about a guy who was mad at a local bank and put a salmon in his safe-deposit box. The bank had to jump through a bunch of legal hoops to get the box drilled over his objections. “It was a prize salmon.”
Heard that too..only with shrimp. Sounds highly effective but also very shady.
