A man who made spears and shields once came to Akbar's court.
"Your Majesty, nobody can make shields and spears to equal mine," he said. "My shields are so strong that nothing can pierce them and my spears are so sharp that there's nothing they cannot pierce."
"I can prove you wrong on one count certainly," said Birbal suddenly.
"Impossible!" declared the man.
How Did Birbal Proved him wrong ?
