I once read that Mohd Sami, Pakistan fast bowler, tried to provoke Sehwag by saying "seedha bat karo" (bat straight), to which Sehwag retorted, "pahle thum seedha gendh feko" (first you bowl straight!) and kept his cool. We know that Sehwag pulverized Pak bowling and scored a double hundred at Multan.
If our batsmen can condition their mind to look at the opponent sledgers as cartoon characters, then they will have fun and not get irritated.
