Hey JG: I wish I have a curiosity like those of childhood now !!! I don't mean that I don't have now, but relatively most of my curiosity are solved by now, the remainings are the second-hand curiosities. LOL... Bothe Necessity and the Curiosity should be the mother of invention: why only credited "Necessity" only right??? Raghav, Hemant and you John seem like created a Gung-Ho-Battalion during that time, huh !!! Nature's Call & Shakti Kapoor Theory were quite a hillarious one..... HD
