There are three construction workers on top of a building having lunch. One Italian, one Polak, and one Oriental.The Italian has a meatball hero, the Oriental has noodles, and the Polak has knockwurst. The Italian and the Oriental are tired of having the same lunches everyday. The Italian says that if he gets a meatball hero the next day that he will throw it off the building. The Oriental says that if he gets noodles tommorow he will also throw it off the building. The Polak says that if he gets knockwurst tommorow he will throw it off the building.Sure enough the Italian and Oriental workers open their lunch-boxes and they find that they have a meatball hero and noodles respectively. They both throw their lunches off the building. The Polak then throws his sandwich off the building.The other guys ask him how he knew that it was knockwurst again without even looking.He responded by saying, „Because I pack my own lunch.“
