"I've never been good at sitting still."

Martin Crane

"I'm a man, and men don't have feelings."

"You know what? I don't need this. I'm going to go sit in my chair."

"That's the problem with you educated types - you're always thinking."

"I've been shot at, I've been stabbed, and I've been poisoned. A little criticism doesn't bother me."
