Many of his family members, fans, friends and co-stars have been recalling his memories on certain occasions. On April Fool's Day, actor Sahil Vaid walked down the memory lane to share how Sushant had once tried to prank him on the sets of "Dil Bechara". âSushant was a science buff. He loved sharing information about the subject with people around him, and one day he decided to pull a prank on me with his 'science ka gyaan'. I remember he came to me with a paper in his hand. He had written a lot of equations on it. His main motive was to make me believe that Albert Einstein's theory of relativity is wrong. He was talking non-stop about the theory.
