I Have A Fairy By My Side Which Says I Must Not Sleep, When Once In Pain I Loudly Cried It Said "You Must Not Weep" If, Full Of Mirth, I Smile And Grin, It Says "You Must Not Laugh" When Once I Wished To Drink Some Gin It Said "You Must Not Quaff". When Once A Meal I Wished To Taste It Said "You Must Not Bite" When To The Wars I Went In Haste It Said "You Must Not Fight". "What May I Do?" At Length I Cried, Tired Of The Painful Task. The Fairy Quietly Replied, And Said "You Must Not Ask". Moral: "You Mustn't."
