Wouldn't it be funny if there was a proverb that went:

"The best babies have the slowest mommies."

Which is to say, the best ideas/things take the longest to come into fruition, a perfectly adequate idea to express in proverb form. But I love how awkward the image of a slow mommy is. And the idea that there is such a thing as a 'best baby.' Overall, the phrase makes sense, but good lord the analogy is flawed all over the place.

Oh, man, I'm going to have some more coffee.
