Buffaloed

"Buffalo buffalo, Buffalo buffalo buffalo, buffalo Buffalo buffalo."

Believe it or not, that's a legitimate sentence. Using three different words spelled "buffalo," the city, the animal, and the action, this forms a complete sentence. Stated differently it says, "Bison from Buffalo, New York, who are intimidated by other bison in their community, also happen to intimidate other bison in their community." Or by replacing the animal with the word "people" and the action with the word "intimidate" you get the following: "Buffalo people [that] Buffalo people intimidate [also happen to] intimidate Buffalo people."

Saying it out loud with proper inflections is all kinds of giggle-inducing fun. Grammar nerds can also diagram the sentence for extra credit.
