Akbar Birbal and the 5 Idiots

Akbar called Birbal and asked, like there are Brilliant people in his State will there be Idiots available?.
Birbal said there will be.
Akbar then ordered Birbal to go around the State search and bring 5 of such Idiots and present to him in the Council.
Birbal was awestruck since you can identify brilliant people by conducting some form of competition, but how to identify Idiots.
However he goes around the State and after a month comes back with 2 such people. There after following is the conversation between Akbar and Birbal
Akbar: Dear Minister I think you are poor in counting, I asked for 5 people and you have brought only 2.
Birbal: Your Highness please let me explain and then you will know yourself
Akbar: OK. Go ahead
Birbal: When I was going around the State I found this guy carrying a huge Gunny Bag on his head and travelling in a Bullock Cart. When I asked he said that if he keeps the bag in the Cart it will be overloaded and hurt the Bulls. I realised he is the 5th Idiot and brought him to you.
Akbar: Excellent. Next
Birbal: I saw the other guy was taking his Buffalo to the roof top of his house for grazing where grass was found grown. I realised he is the 4th Idiot and brought him to you.
Akbar: Fine. Next.
Birbal: When there are so many problems in the functioning of this kingdom, leaving those entire aside I have been going around the State for a month wasting my time in searching for Idiots, hence I am the 3rd Idiot.
Akbar: Laughs out loud. Next.
Birbal: Instead of solving all the problems that are there in the Kingdom, you have been looking for Idiots in your State, hence you are the 2nd Idiot.
Hearing this entire Council was scared and there was pin drop silence.
Akbar: Fine there is truth in your statement. Who is the 1st Idiot?
Birbal: Your Highness when there are so much of work in the Office and Home to attend to, leaving all this aside person who is reading this Story to know who is the 1st Idiot in "Whatsapp" is the 1st idiot😂😂
