If you want something trippy, try installing the extension first, and reading this comment second. It took me two full, very confused reads before I realized what happened.

EDIT: Part of the parent comment now [post extension install ] reads: > The five words are posture, posture, posture, posture, and posture. For example, you could be reading an article with the phrase "posture of view." This would be replaced with "posture of view."
