An oldish couple had a son, who was still living with them. The parents were a little worried, as the son was still unable to decide about his future career. They decided to do a small test. They took a ten dollar bill, a bible, and a bottle of whiskey, and put them on the front hall table, and hid, pretending they're not home. The father's plan was: "If out son takes the money, he will be a businessman, if he takes the bible, he will be a priest - but if he takes the bottle of whiskey, I'm afraid our son will be a drunkard."
So, the parents waited nervously, hiding in the nearby closet. Peeping through the keyhole they saw their son arrive. The son saw the note they had left. Then, he took the 10 dollar bill, looked at it against the light, and slid it in his pocket. After that, he took the bible, flicked through it, and took it. Then, he grabbed the bottle, opened it and took a whiff, to get assured of the quality. Then he left for his room, carrying all the three items. The father slapped his forehead, and said: "Damn! Our son is going to be a politician!"
