I asked the professors who teach the meaning of life to tell      me what is happiness. And I went to famous executives who boss the work of      thousands of men. They all shook their heads and gave me a smile as though      I was trying to fool with them And then one Sunday afternoon I wandered out along      the Desplaines river And I saw a crowd of Hungarians under the trees with      their women and children and a keg of beer and an      accordion.
