My new favorite sentence --

and yes, it is a grammatically correct sentence: Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo.

and coming in second place: "Wouldn't the sentence 'I want to put a hyphen between the words Fish and And and And and Chips in my Fish-And-Chips sign' have been clearer if quotation marks had been placed before Fish, and between Fish and and, and and and And, and And and and, and and and And, and And and and, and and and Chips, as well as after Chips?"

:)

It's all in the delivery.
