An armed robber broke into a house and found a couple sitting at their dining room table. Pointing the gun, he said, "Let me know the names of my victims before I kill them".
Wife: My name is Eunice
Robber: Oh. My mother's name is Eunice. I can't kill you. (Pointing the gun to the man) And you ?
Husband: I'm Joseph, but all my friends call me Eunice.
