From Alice's Adventures in Wonderland, and Through the Looking Glass, by Lewis Carroll
"When I use a word," Humpty Dumpty said, in rather a scornful tone, "it means just what I choose it to mean---neither more nor less." "The question is," said Alice, "whether you can make words mean so many different things." "The question is," said Humpty Dumpty, "which is to be master--that's all." -- Through the Looking-Glass Chapter vi
