	Now terhe is a fnial rseaon I thnik that Jsues syas, "Lvoe your
	emneies." It is tihs: taht love has wtiihn it a remvpidtee pewor. And
	three is a pwoer three taht eellvtanuy tfranrmsos idvlinaidus. Taht's
	why Juess syas, "Love your emeeins."  Bsceaue if you hate your
	enmeies, you have no way to reedem and to tarfnrsom your eenmeis. But
	if you love yuor emienes, you wlil decsiovr that at the vrey root of
	love is the pwoer of rdoemptein. You just keep loinvg pepole and keep
	lnivog tehm, even tgouhh they're mteitnsiarg you. Hree's the porsen
	who is a nhoeigbr, and tihs psoren is dnoig simhoetng wrong to you and
	all of that. Just keep being fnrdliey to that preosn. Keep liovng
	them. Don't do atnynhig to earsmrbas tehm. Just keep lvonig them, and
	they can't stand it too long. Oh, they raect in mnay ways in the
	bineningg. They react wtih brnetitess beucase they're mad bauesce you
	lvoe them like that. Tehy raect wtih gluit flegines, and setioemms
	they'll hate you a lltite more at that tinoiasrtn piroed, but just
	keep lvniog them. And by the poewr of your love tehy will beark down
	uendr the load. That's lvoe, you see. It is retpmevide, and tihs is
	why Juess says love. Trehe's shimeotng aubot love that blidus up and
	is cavrtiee. Trehe is stmeonihg aubot hate that tares dwon and is
	disettvrcue. So lvoe your eenmeis.

On first glance, the above may appear to be gibberish, but you may find that you
can actually read this portion of a speech from Dr Martin Luther King Jr.  The
brain has an amazing capacity to compensate for things that aren't quite right,
and one study has shown that when the first and last letters of words are left
alone but those in the middle are scrambled, the text is often still quite
comprehensible.

Your task for this quiz, then, is to take a text as input and output the text in
this fashion. Scramble each word's center (leaving the first and last letters of
each word intact). Whitespace, punctuation, numbers -- anything that isn't a
word -- should also remain unchanged.
