Two elderly ladies had been friends for many decades.  Over the years, they had shared all kinds of activities and adventures.  Lately, their activities had been limited to meeting a few times a week to play cards.

One day, they were playing cards when one looked at the other and said, "Now don't get mad at me.  I know we've been friends for a long time, but I just can't think of your name!  I've thought and thought, but I can't remember it.  Please tell me what your name is."

Her friend glared at her for at least three minutes;she just stared and glared at her.  Finally she said, "How soon do you need to know?"
