Hobbes:  Do you have an idea for your story yet?
Calvin:  No, I'm waiting for inspiration.
C:  You can't just turn on creativity like a faucet.
You have to be in the right mood.
H:  What mood is that?
C: Last-minute panic.
(Bill Watterson: Calvin and Hobbes, May 21, 1992) 
Calvin:  Here's another math problem I can't figure out.
What's 9+4 ?
Hobbes:  Ooh, that's a tricky one.
You have to use calculus and imaginary numbers for this.
Calvin:  IMAGINARY NUMBERS ?!
Hobbes:  You know, eleventeen, thirty-twelve, and all those.
It's a little confusing at first.
Calvin:  How did YOU learn all this? 
You've never even gone to school!
Hobbes:  Instinct. Tigers are born with it.
(Calvin and Hobbes, January 06, 1988)
