A woman was caught cheating on the spot by her husband, who waved a kitchen knife and asked her, "What do you want to say before you die?"
Wife: "As of now, if you want to kill me, kill me. I do not believe in a person who does not keep the promise."
Husband: "When do I not keep my promise?"
Wife: "Didn't you say you won't be back today?"
