The Rabbit/backwards stairs thing is a superstition we've had for years in my immediate family. Most months we miss part - or all - of it, talking to each other before saying the magic words, or running down the steps without a thought. When we do manage to remember, it seems like the coming month will somehow be just a little bit better. When I say "immediate family", it's really just Abe, Zig, and me. Stuart's outgrown the tradition.
Here's a link to a bit of information about the practice. I particularly like the part that mentions FDR as a fan of the weirdness.
