One of the advantages of being disorderly is that one is constantly making exciting discoveries.

Milne’s joke turns a common criticism—being disorderly—into an “advantage.” The humor depends on reframing the frustration of misplacing things as the thrill of discovery: if you never know where anything is, you repeatedly experience the small drama of finding it again. Beneath the wit is a mild philosophical point about perception: the same circumstance can be experienced as irritation or as novelty, depending on one’s attitude. The line also gently punctures the moral superiority often claimed by the tidy, suggesting that the disorderly may at least enjoy more surprises, even if those surprises are self-inflicted.
