Moishe says to his son: "I want you to marry a girl of my choice".
The son says: "I will choose my own bride".
Moishe says: "But the girl is Bill Gates' daughter".
The son answers: "Well, in that case, yes ok".
Moishe then approaches Bill Gates and says: "I have a husband for your daughter".
Bill Gates answers: "But my daughter is too young to get married".
Moishe says: "But this young man is president of the World Bank".
Bill Gates answers: "Ah, in that case, yes ok".
Moishe goes to see his friend, the chairman of the board of the World Bank and says: "I have a young man to be recommended as president".
The chairman answers: "But I already have a president.”
Moishe says: "But this young man is Bill Gates' son-in-law".
The President answers: "Ah, in that case, yes ok."
And that is how successful Jews do business.
