During the second year of my graduation we had a subject called​ C & Data Structures. This asshole of a teacher (who taught programming by just reading the programs out of the textbook ) came to somehow know that I had learnt C & was good at it (some student had gossiped about me in front of him). Everyday when he came in for the lecture he used to call my name & say - "You think you are very smart please come in front & teach C to everyone" for no apparent reason. (I had never showed him that I was good in programming). For almost complete semester I kept silence & he used to laugh & keep me standing for the complete lecture. But one day I was particularly not in a very good mood & he came & said the same thing. I went & taught for the whole lecture & the whole class applauded at the end. The look on his face was priceless 🤣
