Two young blonde women are sitting at a bar in such an obviously celebratory mood that the bartender drifts over intending to offer them a drink on the house. When he gets close he hears one say to the other "Here's to 17 days!"

Smiling, the bartender says, "Congratulations! What's so special about 17 days?"

Eyes twinkling, one of the women explains, "Well, we've been spending our evenings working on a jigsaw puzzle! And it said 3-5 years on the box, but we finished it in only 17 days!"
