A Canadian, a Mexican and a New Yorker go to an expensive French restaurant. The waiter says to them, "Excuse me, gentlemen. We have a shortage of Truffles. No dishes made with truffles are available."
The Canadian asks, "What is a shortage?"
The Mexican asks, "What are truffles?"
The New Yorker asks, "What is-- excuse me, gentlemen?"

The question is not, Can they reason? nor, Can they talk? but, Can they suffer?
~Jeremy Bentham
