3 men from 3 countries.

The first says: "My country has mountains and valleys and soil perfect for the vine. Our women are the most beautiful in the world and the boys are always willing. No one ever built buildings as beautiful as ours and our craftsmen are the best in the world."

The second says: "We don't wine we drink whiskey, and your women are weaklings good for nothing but chatter, just like your poets who write about nothing. And who's interested in boys? Anyway your mountains suck more than your boys do. There's not enough snow and too many rocks. How can I ski on that?"

The third looks at the others and nods. Then he pulls out a calculator and types a few figures before he speaks: "Logic" he says "shows that mine is the necessary country."
