Låter som den klassiska Martians Go Home av Fredric Brown . En recension säger
The martians, and there are millions of them, have come to earth not to conquer, but to amuse themselves. They can teleport anywhere they want and see through objects. But anyone who tries to kick a martian finds their foot going through empty space. The martians have no material substance. Mass chaos breaks out as humanity has to concern itself with little green men who appear everywhere, making fun of people.
