CALVIN: They say the world is a stage. But obviously the play is unrehearsed and everybody is ad-libbing his lines.
HOBBES: Maybe that's why it's hard to tell if we're in a tragedy or a farce.
CALVIN: We need more special effects and dance numbers.
¶ Calvin & Hobbes (11 Dec 1990)
I'd say that crossed the line from Ironic Coincidence to Evil Omen.
¶ Calvin & Hobbes (11 May 1990)
CALVIN: Well, Hobbes, I guess there's a moral to all this.
HOBBES: What's that?
CALVIN: "Snow goons are bad news."
HOBBES: That lesson certainly ought to be inapplicable elsewhere in life.
CALVIN: I like maxims that don't encourage behavior modification.
¶ Calvin & Hobbes (19 Jan 1991)
CALVIN: The more you know, the harder it is to take decisive action. Once you become informed, you start seeing complexities and shades of gray. You realize that nothing is as clear and simple as it first appears. Ultimately, knowledge is paralyzing. Being a man of action, I can't afford to take that risk.
HOBBES: You're ignorant, but at least you act on it.
¶ Calvin & Hobbes (21 Sep. 1993?)
CALVIN: It's not denial. I'm just very selective about the reality I accept.
¶ Calvin & Hobbes (28 Sep. 1992)
CALVIN (walking through snowy field): You know, Hobbes, it seems the only time most people go outside is to walk their cars. We have houses, electricity, plumbing, heat .... Maybe we're so sheltered and comfortable that we’ve lost touch with the natural world and forgotten our place in it. Maybe we've lost our awe of nature. That's why I want to ask you, as a tiger, a wild animal close to nature, what do you think we're put on Earth to do. What's our purpose in life? Why are we here?
HOBBES: We're here to devour each other alive.
CALVIN (in the house): Turn on the lights! Turn up the heat!
