Sometimes, I replace everyone's garbage cans with recycling bins secretly. Then, after doing it to the entire neighborhood, I throw crushed up cans out the window, sometimes at people, without anyone seeing me. After a bit, pedestrians see these cans and they're like, "Where the hell did all these cans come from?"
They then want to dispose of them. Seeing no garbage cans, they put them in the recycling bins.
Yeah, recycling.
