“ The King of Beasts shouldn't be a coward," said the Scarecrow.
"I know it," returned the Lion, wiping a tear from his eye with the tip of his tail. "It is my great sorrow, and makes my life very unhappy. But whenever there is danger, my heart begins to beat fast."
"Perhaps you have heart disease," said the Tin Woodman.
"It may be," said the Lion.
"If you have," continued the Tin Woodman, "you ought to be glad, for it proves you have a heart. For my part, I have no heart; so I cannot have heart disease."
"Perhaps," said the Lion thoughtfully, "if I had no heart I should not be a coward." ”

“ No one would think of biting such a little thing, except a coward like me," continued the Lion sadly.
"What makes you a coward?" asked Dorothy, looking at the great beast in wonder, for he was as big as a small horse.
"It's a mystery," replied the Lion. "I suppose I was born that way. All the other animals in the forest naturally expect me to be brave, for the Lion is everywhere thought to be the King of Beasts. I learned that if I roared very loudly every living thing was frightened and got out of my way. Whenever I've met a man I've been awfully scared ”

“ If the elephants and the tigers and the bears had ever tried to fight me, I should have run myself—I'm such a coward; but just as soon as they hear me roar they all try to get away from me, and of course I let them go. ”
