Alice: But I don't want to go among mad people.
The Cat: Oh, you can't help that. We're all mad here. I'm mad. You're mad.
Alice: How do you know I'm mad?
The Cat: You must be. Or you wouldn't have come here.
- an excerpt from Alice's Adventures in Wonderland by Lewis Carroll
"Have I gone mad?"
"I'm afraid so. You're entirely bonkers. But I'll tell you a secret. All the best people are."
