There are three construction workers on top of a
building having lunch. One Italian, one Polish, and one Oriental. The
Italian man has a meatball hero, the Oriental man has noodles, and the
Polish man has knackwurst. The Italian and the Oriental are tired of
having the same lunches everyday.
The Italian man says that if he gets a meatball
hero the next day that he will throw it off the building.
The Oriental man says that if he gets noodles
tomorrow he will also throw it off the building.
The Polish man says that if he gets knackwurst
tomorrow 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 Polish man them 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."
