“I've found out why people laugh. They laugh because it hurts so much... because it's the only thing that'll make it stop hurting"...But that's not all people laugh at."Isn't it? Perhaps I don't grok all its fullness yet. But find me something that really makes you laugh sweetheart... a joke, or anything else- but something that gave you a a real belly laugh, not a smile. Then we'll see if there isn't a wrongness wasn't there." He thought. "I grok when apes learn to laugh, they'll be people.”

“I know why we laugh. We laugh because it hurts, and it's the only thing to make it stop hurting.”

“Just because something makes you smile or laugh ... doesn't mean it's a joke.”

“A hundred years from now, people will look back on us and laugh. They'll say, 'You know what people used to believe? They believed in photons and electrons. Can you imagine anything so silly?' They'll have a good laugh, because by then there will be newer better fantasies... And meanwhile, you feel the way the boat moves? That's the sea. That's real. You smell the salt in the air? You feel the sunlight on your skin? That's all real. Life is wonderful. It's a gift to be alive, to see the sun and breathe the air. And there isn't really anything else.”

“He shook his head and gave this laugh, a good laugh, and just looked at me. "You always this happy?""No," I said, laughing. "It's you. Every time I see you, I just...I don't know. You make me smile.”

“Only a short time ago, I learned that people laughed at me. Now I can see that unknowingly I joined them in laughing at myself. That hurts the most.”
