Scientists were finally able to invent a robot that could answer any question.

Paul decided to test the robot as his friends told him about it and he believed that such a robot could not possibly be created.

So he went to the robot, press the button. The robot turned active.

Robot: What is your question?

Paul: tell me where my father is right now.

Robot: your father is right now on the Tuscaloosa university campus.

Paul: Ha Ha. you are wrong. Right now my father is with my mother in Madrid. I just talk to him on phone.

Robot: That chap is your mother’s husband. Your question was about YOUR father.
