Monday's child is fair of face

Prov. A child born on Monday will be good-looking. (This comes from a rhyme that tells what children will be like, according to which day they are born: "Monday's child is fair of face, / Tuesday's child is full of grace, / Wednesday's child is full of woe, / Thursday's child has far to go, / Friday's child is loving and giving, / Saturday's child works hard for a living, / But a child that is born on the Sabbath day / Is blithe and bonny, good and gay.") Joan is so pretty, she must be a Monday's child. Monday's child is fair of face.
