Not parsing it quickthrower2. I get two possible parses:

Bisons (Buffalo) bewilder (buffalo) Buffalo bisons (Buffalo bisons) confuse (buffalo) annoy (buffalo) and vexate (buffalo) other bisons (buffalo).

But that is not grammatical.

Neither is my second parse:

Bisons from Buffalo (Buffalo buffalo) Bisons from Buffalo (Buffalo buffalo) confuse (buffalo) and vexate (buffalo) other bisons (buffalo).

Am I missing it?

You can do this: Buffalo buffalo buffalo buffalo buffalo Buffalo buffalo.

Which is like my first post except each alternative definition of buffalo (confuse, annoy, vexate) is included using the word buffalo in its stead.

But that's just gratuitous.
