For sake of Biriyani !
In Chennai lived an old couple. The man bought a packet of Biryani for himself. While relishing the tasty Biryani his wife began complaining. Without paying any heed he finished the entire packet. He was so angry when his wife kept shouting - that he poured kerosene on her and lighted it with a match stick. While she was burning she retaliated by embracing her husband. They both died. Before death in the hospital the old lady related the entire fact to the attending Doctor !
