I know who you are

A farmer was grazing his animals on a hill. A helicopter suddenly landed there. A pretty likable guy came out of it and talked with the farmer with proud - If I tell you the number of cows, will you give me a calf out of these? Farmers thought a little then said- ok. The man took a gadget out of his pocket and sent a message to Google Map and after doing the calculation found out the answer was 35.
The young man then told the farmer by reducing the number by two - You have 33 cows. Okay - take a calf, the farmer agreed. When the great man began to load a calf in the helicopter, the farmer said- if I tell you your name, will you return my animal? Amused, the man said -okay. Farmer said- You are Rahul Gandhi. Rahul Gandhi was more amused, he asked the farmer- how do you know? The farmer said, very easy-.
* You came uninvited.
* You spent millions of rupees of tax paying people to tell me what I already knew and sir these are not cows but sheep
* And please return my dog that you are trying to load in your helicopter. :P
