Fun with anagrams

I saw that movie The Vanished a few days back, and like a week or two before that, Shutter Island, and then maybe a couple years ago Memento, all of which got me thinking about anagrams in the back of my mind somewhere, I guess, cuz then lo and behold the other day my mind went blank for a while, then when I came to I realized that "saint" and "isn't a" are anagrams, and then I did this thing you always have to do in music theory where you find the different "rotations" of a series of notes, resulting in something like this (only scrawled out in the sort of messy writing indicative of a crackpot revelation in progress):

isn't a saint
(sntasainti)
(ntasaintis)
(tasaintisn)
as ain't isn't
saint isn't a
ain't isn't as
in 'tisn't as a
(ntisntasai)
(tisntasain)
isn't a saint


Then I thought it would be cool to make a poem where you had to use all the five letters before you reused them, but I had to sort of cheat, and it looked like this:

saint isn't a saint
-but-
saint ain't isn't as saint isn't
-so-
ain't a saint a saint?


I dunno, it seemed worthwhile at the time but now it seems like Matty ran out of crosswords and the internet was broke.
