Oz

"I thought Oz was a great Head," said Dorothy.
"And I thought Oz was a lovely Lady," said the Scarecrow.
"And I thought Oz was a terrible Beast," said the Tin Woodman.
"And I thought Oz was a Ball of Fire," exclaimed the Lion.
"No, you are all wrong," said the little man meekly. "I have been making believe."
"Making believe!" cried Dorothy. "Are you not a Great Wizard?"
"Hush, my dear," he said. "Don't speak so loud, or you will be overheard --and I should be ruined. I'm supposed to be a Great Wizard."
