Always a fan of word-play, I recently discovered the most bizarre grammatically-correct sentence:
"Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo."
Check it. Yes, it's a grammatically correct sentence. Consisting solely of the word 'buffalo'.
Don't get it? I don't blame you - it's almost impossible to parse. First, realized that three different meanings of the word 'buffalo' are at play here:
A) buffalo (noun) the animal
B) Buffalo (proper noun) - The city in New York.
C) buffalo (verb) - meaning "to bully or intimidate".
This sentence is about animals from Buffalo bullying other animals from Buffalo, and then being bullied right back. Try reading it with all instances of the animal buffalo being replaced by the word "people" and all instances of the verb buffalo being replaced by the word "intimidate".
"Buffalo people [that] Buffalo people intimidate [also happen to] intimidate Buffalo people."
If that doesn't work, let's try it with clip art.
And so, "Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo."
Get it now? Chew on that. Tomorrow I'll hit you with my second favorite repetitive sentence of all time… one that involves the word "and" being used correctly five times in a row.
