Once, four students spent the whole night partying and did not study for their exam. The next morning, they came up with a plan to avoid the test. They made themselves look dirty with grease and dirt and went to see their professor.
They told the professor that they had gone to a wedding the previous night and, on their way back, a tire of their car burst. They said they had to push the car all the way back and were too tired to take the exam.
The professor thought for a moment and agreed to let them take the exam after three days. The students were very happy and studied hard for those three days.
On the day of the exam, the professor put them in four separate classrooms. The question paper had only two questions:
Your Name? (1 point)
Which tire of the car burst? (99 points)
(Options: Front Left, Front Right, Back Left, Back Right)
Since they had lied, they hadn't discussed this detail. All four students gave different answers. The professor immediately caught their lie and they failed.
Moral of the Story:
Humesha sach bolna chahiye. Ek jhooth ko chhupane ke liye sau jhooth bolne padte hain, aur ant mein pakde jaane par nuksan hi hota hai.
