Legend has it: Never change your bed on Friday; it will bring bad dreams. If you cut your nails on Friday, you cut them for sorrow. Don't start a trip on Friday or you will encounter misfortune. Ships that set sail on a Friday will have bad luck, as in the tale of H.M.S. Friday. One hundred years ago, the British government sought to quell the longstanding superstition among seamen that setting sail on Fridays was unlucky. A special ship was commissioned and given the name "H.M.S. Friday." They laid her keel on a Friday, launched her on a Friday, selected her crew on a Friday, and hired a man named Jim Friday to be her captain. To top it off, H.M.S. Friday embarked on her maiden voyage on a Friday — and was never seen or heard from again.
