Sandy Chipmunk in "Sandy's Name"

Once more Mr. Crow stopped him.

"You don't understand," he said. "I don't want to ask you anything. I want to tell you something."
"Oh!" said Sandy. "That's different. What is it?"
"It's quite a joke," Mr. Crow said. And he laughed loudly. "These young fellows here have been trying to tell one another why you're called Sandy. One of 'em says it's because you like to dig in the sandy soil; and another says it's because of your color; and still another claims it's because you're plucky. But I tell 'em it's because your real name is Alexander. And of course I'm right," said old Mr. Crow.
