Elisabetta Addis just said "Rabbits don't understand topology" and she meant it.

Our pet rabbit was grazing on a long leash which it had managed to loop around various trees, so the comment was practical. It made me wonder if anyone had ever said "Rabbits don't understand topology" in all of human history (pre-history is a snap since prehistoric people didn't talk much about topology).

I'm pretty sure that no one has ever written "rabbits know everything there is to know about topology".
