The Italian – throws the cup, breaks it, and walks away in a fit of rage
The German – carefully washes the cup, sterilizes it and makes a new cup of coffee
The Frenchman – takes out the fly, and drinks the coffee
The Chinese – eats the fly and throws away the coffee
The Russian – Drinks the coffee with the fly, since it was extra with no charge
The Israeli – sells the coffee to the Frenchman, sells the fly to the Chinese, sells the cup to the Italian, drinks a cup of tea, and uses the extra money to invent a device that prevents flies from falling into coffee
The Palestinian – blames the Israeli for the fly falling into his coffee, protests the act of aggression to the UN, takes a loan from the European Union to buy a new cup of coffee, uses the money to purchase explosives and then blows up the coffee house where the Italian, the Frenchman, the Chinese, the German and the Russian are all trying to explain to the Israeli that he should give away his cup of tea to the Palestinian so there will be peace.
