"and inexpensively make your home unattractive"
If you’re planning on making your home unattractive, Horse recommends opening several (or all) windows for ventilation.
My ORIGINAL idea involved an interior decorator walking around pointing at things and saying “Poop. More poop here. Make this poop,” etc etc. And installing a toilet made OUT OF poop.
One day…one day I’ll get to draw such a toilet.
