Sardar Terrorists

There were two Sardarjis Bantya and Santya as bombers. They
had to place a time bomb in order to explode a building. So
they were going on their destination in a car. On their way
Bantya asked Santya, "Santya what will happen if the time
bomb explodes in this car itself." Santya replied
"Don't worry, I have a spare one!!!!!
