Joke: Liar Liar

Two boys were arguing when the teacher entered the room. The teacher says, “Why are you arguing?” One boy answers, “We found a ten Naira 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 boys gave the ten Naira to the teacher.
