Consider the following:
Buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo.
How about this one? “James while John had had had had had had had had had had had a better effect on the teacher.”
Needs quotation marks
Yeah, I always hated that one because it only works because of the (incorrect) omission of punctuation. The Buffalo buffalo one doesn’t need anything except the period at the end to be correct.
Bison*
Didn’t know buffalo was a verb.
It means to bully basically. The sentence can be rewritten as “Buffalonian bison that other Buffalonian bison bully also bully Buffalonian bison.”
Don’t let them buffalo them into believing that tripe.
It gets worse:
Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo
Rochester bison that Rochester bison bully bully Rochester bison
Capitalization is key for this one
“Buffalo buffalo buffalo Buffalo buffalo Buffalo buffalo buffalo” is a tautology but still a sentence
Buffalo: to puzzle or baffle; confuse; mystify
