Why does cows lying down mean rain?

It may be an urban myth, but I've heard that it's only true for
thunderstorms. If lightning strikes the ground near a cow and it is standing
up, there can be enough electrical potential between the front and back legs
of the cow to kill it. If it's lying down the current takes a different
route and it's OK. Sounds far-fetched to me but you never know.
