What does this excerpt from A Christmas Carol by Charles Dickens reveal about Scrooge's childhood? "Why, it's Ali Baba!" Scrooge exclaimed in ecstasy. "It's dear old honest Ali Baba! Yes, yes, I know! One Christmas time, when yonder solitary child was left here all alone, he did come, for the first time, just like that. Poor boy! And Valentine," said Scrooge, "and his wild brother, Orson; there they go! And what's his name, who was put down in his drawers, asleep, at the Gate of Damascus; don't you see him! And the Sultan's Groom turned upside down by the Genii; there he is upon his head! Serve him right. I'm glad of it. What business had he to be married to the Princess!"
