A college economics professor could not help but notice that one of his students was late to class for the third time that week. Before class ended he went around the room asking students some questions about the day's lecture. Of course, he made sure to pick on his student. "And who is known as the father of modern economics?" the professor asked. "I don't know," the student said. "Perhaps if you came to class on time, Mr. Wilson, you would know," said the professor. "That's not true," the student replied. "I never pay attention anyway!"
