What does Chaucer seem to be saying about marriage in "The Miller's Tale?"

Well, you wouldn't want to assume this tale represents Chaucer's position; he takes various positions that don't fit together smoothly in this set of stories. However, this story shows marriage as anything but the sacred bond the church would have it. Marriage is shown as entered into by the ignorant, who don't really know one another. This allows for deception, and makes those involved look stupid. Broadening the question a little, the story shows how sexual desire can make us look like fools.
