Old Mr. Crow in "An Unlucky Number"

"There!" Mr. Crow cried. "There's your coat with the thirteen spots on it! I certainly don't want it, for it has caused me no end of trouble." Then he turned and hurried out of the shop, without stopping even to thank Mr. Frog for what he had done. Before Mr. Crow was out of hearing, the tailor thrust his head through the doorway and called to the departing Mr. Crow. "I told you—" said Mr. Frog—"I told you thirteen was an unlucky number."
