This memory popped into my head after reading about the long-overdue end of the Tesla DumpsterCar era:
Years ago, I tried to throw away a trash can.
I turned it upside down, and it was righted by our helpful trash handlers.
I stacked it on top of another can, and it was carefully placed next to it after emptying.
I finally put a sign on it which read "This is garbage".
The next day the sign was replaced by another one which read, "Yes, we know."
