The medical Examiner was dumbfounded and shocked
By what he saw when he opened her up
The heart was where the brain should be
And in the area where the heart should be was a note
It read the following:

Dear examiner
            I couldn't come up with worthwhile ideas until I left these matters
to the heart. so I took out my brain you see, and replaced it with something far more useful, but unfortunately that has left me in a pickle because I forgot I needed it to breath. I guess being the person I am, matters of the heart were far more important.
                       Sincerely with love,
                                        the dead girl
