Very rarely used by people who are married to ageing mermaids, old wives' tales are superstitions which are untrue and/or totally ridiculous.

Many people maintain that old wives' tales are based on truth, and have merely been distorted by the passage of time. This, however, is probably just an old wives' tale.

The following list of old wives' tales should be taken with a pinch of salt. We accept no responsilibity for the level of luck acquired by following these instructions, the sex of any babies you might be in the process of having, or any ugliness caused by changes in the weather. Life's hard enough already.

Elsewhere, any encounter with a witch is bad luck.
