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