Banta was in the army. During the war with Pakistan, Banta used his
intelligence to kill many Pakistani soldiers. He would hide behind the
bushes and shout Pakistani names like - Imran Khan etc. and the soldier
named Imran Khan would get up to say 'I am here !' Then Banta would shoot him down. This went on till Banta almost wiped out all the soldiers single handedly!
Suddenly the Pakistani commander realized that Banta was killing all his soldiers by fooling them. So he decides to use Banta's own method to kill him and starts calling him names like Banta etc.
Banta realizing that the Pakistani was using his trick,
suddenly says 'Who called me ?' and the Commander gets up to say 'I called you.'
Banta shoots him also down!
