There's a thread somewhere that uses the "Rocks & Gravel make a solid rod" but I don't know where it is.

Takes rocks and gravel, honey, to make a solid road, now sugar
Takes rocks and gravel, honey, to make a solid road,
Well-a, it takes rocks and gravel, honey to make a solid road, now sugar
It take a good looking woman honey to make a good looking whore.
