“What have I eaten? Lies and smiles.”

“First comes smiles, then lies. Last is gunfire.-Roland Deschain, of Gilead”

“I had to smile at the man. I mean, you have to smile at idiots and children.”

“What are you looking at? Hale asked.
Why are you smiling? I worry when you smile.”

“Those who are poor, smile at what they have, yet those who have good fortune, frown at what they do not have.”

“I smile when I'm angry, I cheat and I lie.
I do what I have to do to get by.
But I know what is wrong and I know what is right,
and I'd die for the truth in my secret life.”

“twice I have lived forever in a smile”

“What are you?" I rasped.
It smiled. "Whatever scares you.”

“Camped on a tropic riverside,
One day he missed his loving bride.
She had, the guide informed him later,
Been eaten by an alligator.
Professor Twist could not but smile.
"You mean," he said, "a crocodile."”

“I am ashamed of my century, but I have to smile.”
