Given the potential randomness of poetic fashion, be it contrived or otherwise, it strikes me that a simple punctuation mark can change the entire meaning of a tome. For example, how about one of the few Christmas carols I can stomach: God Rest Ye Merry, Gentlemen.
Now, most people you might ask would tell you that the comma goes after "Ye." Nay. It goes after "Merry," thus taking a song that could be about how comfortable a happy man may leave this world, into a realm of "may you go in peace after struggling against the toils and evils of this world, stuck in a do-nothing existence, buggering when possible and thumbing your nose to no avail against the proletariat." Or something like that.
Just thought I'd stir up an empty pot.
