someone should walk up and set an open jar of skunk essence ion the floor right between them- and claim ‘it’s performance art- just watch their performance”
Where’s the little glass stink bombs when you need them?
No. Just leave them there until they get hungry or have to pee or poop. And then keep leaving them there.
If the painting is damaged, make them work to pay for it - probably for most of the rest of their lives.
There is a product called “Liquid Ass” which is particularly horrifying. The only problem is the stinky activists are probably use to the smell. But would still be fun to apply liberally...
