"True" Teacher

"True"  Teacher

Two students were arguing when the teacher entered the room.
The teacher says, "Why are you arguing?"

One boy answers, "We found a hundred rupee note  and decided to give it to whoever tells the biggest lie."

"You should be ashamed of yourselves," said the teacher, "When I was your age I didn't even know what a lie was."

The students gave the hundred rupee note to the teacher.
