Smart Father

Father:    “I want you to marry a girl of my choice”.
Son:          "I will choose my own bride!"
Father:      "But the girl is Bill Gates' daughter."
Son:          "Well, in that case, OK"

Next:         Father approaches Bill Gates.

Father:      "I have a husband for your daughter."
Bill Gates:   "But my daughter is too young to marry!"
Father:      "But this young man is a vice-president of the 
                 World Bank." 

Bill Gates:  "Ah, in that case, OK"

Finally, Father goes to see the president of the World Bank.

Father:     "I have a young man to be recommended as a vice-

                president."
President: "But I already have more vice- presidents than I need!"
Father:     "But this young man is Bill Gates's son-in-law."
President: "Ah, in that case, OK"
