Read this excerpt from Through the Looking-Glass by Lewis Carroll. "I'm sure I'm very sorry,” was all Alice could say; for the words of the old song kept ringing through her head like the ticking of a clock, and she could hardly help saying them out loud:

"Tweedledum and Tweedledee
Agreed to have a battle;
For Tweedledum said Tweedledee
Had spoiled his nice new rattle.

Just then flew down a monstrous crow,
As black as a tar-barrel;
Which frightened both the heroes so,
They quite forgot their quarrel.”

"I know what you're thinking about,” said Tweedledum; "but it isn't so, nohow.”
