Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo

So the criteria for this to work is that a word needs to be all of the following;

1. A proper noun representing a place (Buffalo, NY) 2. A verb (to buffalo, to bully or harass) 3. A noun whose plural is the same as it's singular (a buffalo, many buffalo)

Badger almost works but it's plural is badgers.

Moose almost works but moose isn't a verb.

I think Smurf works.

For 1., looks like any adjective works as opposed to just proper nouns representing places.

Also, for 3. seems like all the nouns are plural, so the singular and plural forms don't necessarily have to match.

A translation:

New York bison which New York bison bully also bully other New York bison.

Norwegian one: (fisker fisker fisker fisker fisker)*
