A student applied for university and had to do an interview.

The interviewer thought the boy was very smart and since he could answer all the questions correctly, he decided to corner the boy with an impossible question.

“For this next section, I can either ask you ten easy questions or one really difficult question. Think hard before you make up your mind,” said the interviewer.

The boy thought for a while and said: “I choose one really difficult question.”

“Well, good luck to you! Tell me: What comes first, day or night?”

The boy thought for a long while before confidently answering: “It’s the day, sir.”

Confident that he’d tricked the boy, the interviewer asked: “How did you find that out?”

The boy shrugged and answered: “Sorry sir, you promised me you would only ask one difficult question!”
