Grey's Anatomy, Season 2

Meredith:
[voiceover] Superstition lies in the space between what we can control and what we can't. Find a penny, pick it up, and all day long you'll have good luck. No one wants to pass up a chance for good luck, but does saying it thirty three times really help? Is anyone really listening? And if no ones listening, why do we bother doing those strange things at all? We rely on superstitions because we're smart enough to know we don't have all the answers. And that life works in mysterious ways. Don't diss the juju, from wherever it comes.
