Buffalo

While I was wasting time today I came across this sentence which, by the way, is grammatically correct and is meaningful:

Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo.

If you have seen this before, it is awesome, huh? If you have not seen it before, try and figure it out for a while.

Hint #1: Buffalo is used as the city, bison, and bully here.
Hint#2: I don't have any more hints now. Here is another way of writing it:

The bison from Buffalo that bison from Buffalo bully also bully bison from Buffalo. Cool huh?


I also found another sentence that looked crazy. This one is not punctuated correctly, but it is still pretty neat:

James while John had had had had had had had had had had had a better effect on the teacher.

If you haven't seen it before, I think it is impossible to decipher.
With punctuation the sentence reads:

James, while John had had "had", had had "had had"; "had had" had had a better effect on the teacher.


Another sentence without correct punctuation:

That that is is that that is not is not is that it it is

with punctuation it would read:

That that is, is. That that is not, is not. Is that it? It is.


And then I found some garden path sentences. I already knew this one:

The horse ran past the barn fell

meaning, the horse fell and the horse ran past the barn, but I hadn't seen some of these others, and I thought they were cool:

The farmer threw the cow over the fence some hay


The old man the boat

Very busy day at the jail today...
