Apparently saying "rabbits" or "white rabbits" three times as the first thing you say on the first day of a month is supposed to bring good luck. I've never actually remembered to do this at the beginning of a month, so I can't attest to whether it does actually bring good luck.
I really love this collection of cast iron rabbits who hang out under a bench. Their original purpose may have been doorstops but I think they make quite a statement lined up in a row like this nowhere near a door.
