Who needs enemies

JoAnn was a busy housewife with a demanding husband, six children and a large house. The only relief JoAnn got from her chores was the twice-a-week bridge game she shared with a dozen other women.
The only flaw in the bridge club relationship was that JoAnn loved to tell off-color stories and the girls didn't want to hear them.
To teach JoAnn a lesson, the other women decided that the next time she told an off-color story, they'd just get up, walk out, and meet at another home but without her.
Sure enough, at the next bridge club meeting, JoAnn started, "You know, girls, there's a rumor going around that a busload of prostitutes will be leaving in the morning for that big gold find up in Alaska, and they say . . . " Just then, the women all stood up and started for the door.
JoAnn was disconcerted, but only for a moment. Then she understood what was going on and said, "Hey! Girls! Hold on, hold on! There's plenty of time because the bus doesn't leave until morning!"
