"You are sad," the Knight said in an anxious tone: "let me sing you a song to comfort you.... The name of the song is called 'Haddocks' Eyes.'"
"Oh, that's the name of the song, is it?" Alice said, trying to feel interested.
"No, you don't understand," the Kinght said, looking a little vexed. "That's what the name is called. The name really is 'The Aged Aged Man.'"
"Then I ought to have said, 'That's what the song is called'?" Alice corrected herself.
"No, you oughtn't: that's another thing. The song is called 'Ways and Means': but that's only what it's called, you know!"
"Well, what is the song, then?" said Alice, who was by this time completely bewildered.
"I was coming to that," the Knight said. "The song really is 'A sitting on a Gate': and the tune's my own invention."
