Buffalo buffalo buffalo buffalo.

Bison from upper New York bamboozle other buffalo.

No matter how many 'buffalo's you string together, you get a grammatically correct sentence. Try it. Just keep saying 'buffalo' over and over for a week, and it'll mean something. Not a lot, mind you... ain't gonna get no novel published that's just one word over and over... unless maybe you're James Joyce. Still, you'll make a sentence that makes sense. Ever smaller groups of hoofed mammals intimidating and confusing an increasing number of such groups who, in turn, do the same to even further subdivisions thereof, some of whom live upstate of me.

I love this language.
