One morning, on a working day, Mulla Nasrudin was seen leaving the workplace during working hours.
“Where are you going?” the Boss asked Nasrudin as he saw him walking out of the workplace.
“I am going to the barbershop to have a haircut,” Nasrudin answered.
“You can’t go for your haircut in working hours!” the Boss thundered.
“Why not? I grew my hair in working hours,” Nasrudin argued.
“Not all of it. You did not grow all your hair in working hours,” the Boss countered.
Mulla Nasrudin gave the Boss a triumphant look and said, “Okay, I shall tell the barber to cut only that much hair that grew in working hours!”
