At the station, the three Aussies each buy a ticket and watch as the three New Zealanders buy just one ticket between them. “How are the three of you going to travel on only one ticket?” asks one of the Aussies. “Watch and learn,” answers one of the New Zealanders.
They all board the train. The Aussies take their respective seats but all three New Zealanders cram into a toilet and close the door behind them.
Shortly after the train has departed, the conductor comes around collecting tickets. He knocks on the toilet door and says, “Ticket please.”
