"Up with which I shall not put"

[for fun friday]

"Up with which I shall not put" is writer's cul-de-sac,
Overthought and overwrought with which the mind to pack;
If Churchill's quip was his or not, it's lesson has been taught,
And in this matter poet's whim is plot abiding not.

Words are ordered not or with all prepositions in,
The rightful place along the way but never at the end;
But when we strain the syntax sore by unencumbered will,
We think we'll never see much worse the end of time until.
