Homographs have fascinated me for quite a while. So far, I've only been able to assemble one homographic sentence, and it's not the best example thereof as the final word does not strictly have to change. It amuses me to think that the pronunciation of the whole sentence is dictated by the closing punctuation. Not only that, but the first three words change parts of speech.

Does lead wound bass?
An environmental question best left to an ichthyologist.

Does lead wound bass!
Several female deer guide an entangled opera singer.

Got any others?
