The paradox of dog territory ownership during and after it rains.
Rain washes away or spreads out the scent of
piss, so it has to be replaced eventually, but as there is no longer any record of the pisser'
s claim, does it truly have the right to claim it again? This thought experiment was first proposed by Robert Hund in 1933 because he probably ran out of things to do in his tiny Hooverville cabin and had to start tracking the territory of neighborhood
dogs during his waking hours. He's also proposed the swallowing tree paradox, the ripened
banana and blue pen ink paradox, and to his
wife, Melanie. She once gave her grandson $1 to "buy himself something nice" with, back when that meant something.
