Cheshire Cat quotes which I like

Cheshire Cat "`Cheshire Puss,' [Alice] began, rather timidly, as she did not at all know whether it would like the name: however, it only grinned a little wider. `Come, it's pleased so far,' thought Alice, and she went on. `Would you tell me, please, which way I ought to go from here?'
`That depends a good deal on where you want to get to,' said the Cat.
`I don't much care where--' said Alice.
`Then it doesn't matter which way you go,' said the Cat.
`--so long as I get SOMEWHERE,' Alice added as an explanation.
`Oh, you're sure to do that,' said the Cat, `if you only walk long enough.'"

"`But I don't want to go among mad people,' Alice remarked.
`Oh, you can't help that,' said the Cat: `we're all mad here. I'm mad. You're mad.'
`How do you know I'm mad?' said Alice.
`You must be,' said the Cat, `or you wouldn't have come here.'
Alice didn't think that proved it at all; however, she went on `And how do you know that you're mad?'
`To begin with,' said the Cat, `a dog's not mad. You grant that?'
`I suppose so,' said Alice.
`Well, then,' the Cat went on, `you see, a dog growls when it's angry, and wags its tail when it's pleased. Now I growl when I'm pleased, and wag my tail when I'm angry. Therefore I'm mad.'"
