IV.
One day the Khalif Harun-ar-Rashid and his jester, the poet Abu Nuwas, were disputing as to the truth of an axiom laid down by Abu Nuwas, that 'an excuse was often worse than the crime,' and the poet offered to convince the monarch of it before the night was over. The Khalif, with a grim humour peculiarly his own, promised to take off his jester's head if he failed to do so, and went out in a rage. After awhile Harun came in a somewhat surly temper to his harem, and the first thing which greeted him was a kiss from a rough-bearded face. On calling out violently for a light and an executioner, he found that his assailant was Abu Nuwas himself. 'What on earth, you scoundrel, do you mean by this conduct?' asked the enraged Sovereign. 'I beg your Majesty's most humble pardon,' said Abu Nuwas, 'I thought it was your Majesty's favourite wife.' 'What!' shrieked Harun, 'why the excuse is worse than the crime.' 'Just what I promised to prove to your Majesty,' replied Abu Nuwas, and retired closely followed by one of the imperial slippers.
