I can't say I have seen anything else that Kunal may have done other then BBT. In saying so he is great, he brings the character to life and made for awesome laughing moments. As of now his character drinks to talk to women so you tend to see his character drink too much. I wonder when he will come out as a drunk or when they will give his character the freedom of talking to women without being drunk, and a jerk as seen many times. Great character but he is stuck in a character trap that prevents character evolution. Writers fault, not Kunal.
