I was delighted to discover, on Digg.com the other day, what is surely the strangest grammatically correct sentence in the English language: Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo!!! It was invented in 1972. Ah those cunning linguists!
It took me a few minutes to figure out. Obviously, the word buffalo is used as a proper noun (the city in upstate New York), as a noun (bison), and a very ("to bully"). What threw me is that the middle of it is an inner clause; I'm not used to reading (or forming) clauses like that without punctuation or joining words. If you get the intonation right, it makes sense.
So it can be best understood as: Buffalo bison [whom] Buffalo bison bully[,] bully Buffalo bison. Or, in a shorter (only singly reflexive version):
Buffalo bison bully Buffalo bison (Buffalo buffalo buffalo Buffalo buffalo)!
