Three Canadians and three Americans are traveling by train to a hockey game.

At the station, the three Americans each buy tickets and watch as the three Canadians buy only a single ticket.

"How are the three people going to travel on only one ticket?", asks an American.

"Watch and you'll see," says a Canadian.

They all board the train. The Americans take their respective seats but all three Canadians 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 a crack, a single arm emerges with a ticket in hand. The Conductor takes it and moves on. The Americans see this and agree it was quite a clever idea.

So after the game they decide to copy the Canadians 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 Canadians don't buy a ticket at all.

"How are you going to travel without a ticket?" asks one perplexed American.

"Watch and you'll see", replies a Canadian.

When they board the train the three Americans cram into a bathroom and the three Canadians cram into another bathroom nearby. Once the train leaves the station, one of the Canadians leaves and walks over to the other bathroom where the Americans are hiding, knocks on the door and says, "Ticket Please".
