It all begins when Munna is born inconveniently just one or two months late for LKG or UKG admissions cut-off in a given year. So the parents concoct an “official” birthday that’s one or two months earlier (carefully counting three-four times from their wedding date), so that their darling chut-put will not waste his time running around nunga-punga when he could be getting a serious education and be on his way to taking the IIT-JEE one year early. Imagine, he will always be-ahead-in-life!
And so all the paperwork from then reflects this fake birthday: school records, passport, driving licence, and eventually—oh so inevitably, given that Munna had this shiny headstart—his H1B visa application for America-based employment purposes.
She: What, you don't know your own birthday?
Munna: I'm trying to remember which one's my real birthday.
She: Check please!
