Vishwajit Singh was an old friend of Rajiv from the Doon School days. He is big-built man, weighing over 200 Kg. A Haryana Congress leader had proposed to Rajiv for a blood donation campaign based on one's weight'. And in a mood of prank, Rajiv sent the Haryana leader to his Private Secretary V.George, asking him to introduce him to Vishwajit, who"could himself donate blood equal to 10 donors".
