A million or so years ago I was involved with a stunt where we had a plant in a local park-like space.
She gave every sign of falling asleep in the sun with a book.
A white van pulled up and disgorged a group of people in Tyvek suits and respirators. They put her in a body-bag, sprayed down the grass where she had been stretched out, and took the bag back to the van and drove off.
