The Lion and the Unicorn

From the script: 

 "HAIGHA. They're at it again!

 WHITE KING. (Jumping up and shaking himself.) Do you call that a whisper? If you do such a thing again, I'll have you buttered! It went through and through my head like an earthquake!

 ALICE. Who are at it again?

 WHITE KING. Why the Lion and the Unicorn, of course.

 ALICE. Fighting for the crown?

 WHITE KING. Yes, to be sure, and the best of the joke is, that it's my crown all the while! Let's run and see them.

 ALICE.

  The Lion and the Unicorn were fighting for the crown: 
 The Lion beat the Unicorn all round the town. 
Some gave them white bread, some gave them brown; 
 Some gave them plum-cake and drummed them out of town."

p 50

Historical Background: 

 “The Lion and the Unicorn lyrics date from 1603 when King James VI of Scotland became James I of England unifying the Scottish and English kingdoms…The union of the two countries required a new royal coat of arms combining those of England, which featured two lions, and Scotland, whose coat of arms featured two Unicorns…A compromise was made thus the British coat of arms has one Lion and one Unicorn and the poem about "The Lion and the Unicorn" was created” (rhymes.org.uk).
