can you not concentrate during exam

It was the month of march and the school and college exams were approaching,
a group of boys staying in hostel were not able to concentrate on their reading due to girls
and under tension they decided to go to temple and take assistance of their swamy.
The swamy was very experienced and knew the exact solution for it;
He instructed to close their eyes and say "om shanti om"
whenever they saw a beautiful girl!
a few days later they were all sitting in a garden and reading
suddenly one of them said "om shanti om"
and as per the tendency of boys all of his friends asked him "where where???"
boyz r boyz :D
