A Frenchman, a German and a Jew are walking through a desert. It is very hot and they have no water.
After a few miles the Frenchman falls to his knees in the sand and declares, “I’m hot, I’m thirsty, I’m tired. Je demande some really good French wine.”
A little later the German pulls up smartly, stands to attention and says, “I’m hot, I’m thirsty und ich bin tired. I must have some really good German beer.”
Later still the Jew stops dead in his tracks and says, “I’m tired, I’m hot and I’m thirsty. I must have diabetes.”
Also: why are Jewish men circumcized? Because no self-respecting Jewish woman will accept anything that doesn’t have 20% off.
