One year, a traveling ballet troupe decided to perform Swan Lake. It spent months rehearsing. Two days before hitting the road, it held a dress rehearsal. Unfortunately, moths had gotten into the tutus. They were destroyed. And there was no place in town to buy new ones. So the producer called around to neighboring cities. Eventually, a shop promised to deliver tutus by train the next day. The producer went to the train station to await delivery. The stationmaster noticed him and asked if he needed help. ?No,? he replied. ?I?m just waiting for the tutu train.?
