supporters are traveling by train to a Cup Final in Cardiff. At the station, the three Arsenal supporters each buy tickets and watch as the three Chelsea supporters buy only a single ticket. "How are three people going to travel on only one ticket?" asked one of the three Arsenal supporters. "Watch and you'll see," answers one of the Chelsea supporters. They all board the train. The Arsenal supporters take their respective seats but all three Chelsea supporters cram into a restroom and close the door behind them. Shortly after the train as departed, the conductor comes around collecting tickets. He knocks on the restroom door and says, "Ticket, please." The dooropens just a crack and a single arm emerges with a ticket in hand. The conductor takes it and moves on. The Arsenal supporters saw this and agreed it was quite a clever idea. So after the Cup Final in Cardiff, the Arsenal supporters decide to copy the Chelsea supporters on the return trip and save some money. When they get to the station, they buy a single ticket for the return trip. To their astonishment, the Chelsea supporters don't buy a ticket at all. "How are you going to travel without a ticket," asks one perplexed gooner. "Watch and you'll see," says one of the Chelsea supporters. When they board the train the three Arsenal supporters cram into a restroom and the three Chelsea supporters cram into another one nearby. The train departs. Shortly afterward, one of the Chelsea supporters leaves his restroom and walks over to the restroom where the Arsenal supporters are hiding. He knocks on the door and says, "Ticket, please."
