Rabbit Rabbit

A friend of mine just told me about a superstitious custom where, on the first of the month, the first thing you say is “Rabbit Rabbit” to bring you luck. I thought she had made it up, but Lo! There is an article regarding the custom on Wikipedia! I love these kinds of mysterious customs, especially the lucky ones. The problem is: now I want to say “rabbit rabbit” all the time. I can imagine my sis and I rabbit rabbiting at each other all day long, if we’d known about this when we were kids.
