A mad man was walking through a street and saw an SUV, written on the car was 4×4. The mad man laughed and said ‘na wa o, so nobody fit solve this maths?’ He picked up a stone and wrote on the car =16, when the owner of the car came out later and saw it he screamed, cursed and shouted thinking it was the street kids. He called a spray painter to respray the car the next day, after some days the mad man was passing that same route and saw the car and said ‘na wa o, because I answer question last time now everybody dey keep question for me’. He took a stone and repeated the same act, when the owner of the car came out he was almost mad. He called the spray painter again and this time with a fine artiste who wrote =16 after the 4×4 on the car. A few days later the mad man was still passing the same route and saw the car and said ‘yes now you it right’ picked up a stone and ticked it right and wrote ‘very good’.
