Bob and Betty Old Friends
Bob and Betty, two life long friends, now in their 80's, met once a week to play cards and discuss life and everything.
One day durinng a game of gin rummy, Betty says, "I'm sorry, I know we've been friends for many years, but my memory fades. For the life of me, I can't remember your name."
Bob smiled knowingly and sat silently for a few minutes... "How soon do you need to know?" he replied.
