Believe it or not, this is a proper English sentence:
Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo.
In fact any occurrences greater than zero is a proper sentence. If you are into geek notation this is what it means:
Buffalo [buffalo...].
To find out what the sentence really means you can check out the Wikipedia page, Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo, where they can explain it a lot better than I can.
Also because the English language is so random, people think they can do whatever they want with it to make it proper, see this blog that documents unnecessary quotation marks.
What about the letter case?

Ah you got me there. But if you leave out the city “Buffalo” and keep repeating the word “buffalo” you will get something like this:
Buffalo.
“Engage in bamboozlement.”
Buffalo buffalo.
“American bison are characteristically given to engaging in bambloozlement.”
Buffalo buffalo buffalo.
“American bison are characteristically given to bamboozling other members of their species.”
Buffalo buffalo buffalo buffalo.
“American bison habitually bamboozled by members of their own species (that is, buffalo whom other buffalo regularly buffalo) characteristically engage in bamboozlement.”
Buffalo buffalo buffalo buffalo buffalo.
“American bison habitually bamboozled by members of their own species (that is, buffalo whom other buffalo regularly buffalo) tend to return the compliment by bamboozling in turn yet other members of the species.”
Buffalo buffalo buffalo buffalo buffalo buffalo.
“American bison habitually bamboozled by members of their own species that have themselves been bamboozled by others of their ilk (that is, buffalo whom other buffalo who have themselves been buffaloed by buffalo regularly buffalo) tend to engage in bamboozlement.”
Buffalo buffalo buffalo buffalo buffalo buffalo buffalo.
…
So I think the shortened man style geek comment is correct “Buffalo [buffalo].”
