"One, two, buckle my shoe; Three, four, knock at the door; Five, six, pick up sticks; Seven, eight, lay them straight; Nine, ten, a big fat hen; Eleven, twelve, dig and delve; Thirteen, fourteen, maids a-courting; Fifteen, sixteen, maids in the kitchen; Seventeen, eighteen, maids in waiting; Nineteen, twenty, my plate's empty."
