"A Boy Named Sue"

I think that the song "A Boy Named Sue" heavily relied on the form of casualty, which tells one event that occurs because of another event. It uses that to continue a story along very nicely. For example, each new verse just tells a different part of the life of Sue, until we arrive at the part where his dad shows up and talks to him. The story is told brilliantly this way up until the very end. Then he says how he hates the same Sue for a boy, and he will never name his boy that, but anything else first.
