Similarly, in the Prologue to the Canterbury Tales, a young squire is described as conducting himself "in hope to stonden in his lady grace" (in the hopes of standing in his lady's grace).

Some take this to be a bawdy anatomical pun, expressing the young man's hopes of 'standing' in his lady's 'grass' — a distinction lost nowadays that the pronunciation of "grace" and "grass" have grown so far apart.
