Two ladies have played bridge together for years. Naturally they had gotten to know each other pretty well. One day during a game one lady suddenly looks up at the other and says, "Now dear I know that we've known each other for many years, but please don't be angry or upset by this. Could you please tell me your name? I'm trying to remember, but I just can't bring it to mind."

The other lady glares at her for a full three minutes and replies, "How soon do you need to know?"
