Read this excerpt from Through the Looking-Glass by Lewis Carroll Shortly after Alice sings this song. Tweedledee and Tweedledum begin to battle This is evidence that "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 - walking backward means going forward in the looking-glass land one has to run quickly in order to stand still in the looking-glass land O fictional characters are real in the looking-glass land things happen only every other day in the bar "Tweedledum and Tweedledee Agreed to have a battle, For Tweedledum said Tweedledee Had spoiled his nice new rattle glass land Just then flew down a monstrous crow As black as a tar-barrel Which frightened both the heroes so, They quite forgot their quarrel."
