Three Pakistanis and three Americans are traveling by train.At the        station, the three Americans each buy tickets and watch as the three
Pakistanis 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," answers a Pakistanis.
      
They all board the train. The Americans take their
respective seats but all three Pakistanis 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.
      
Americans see this and agree it was quite a clever
idea.
So after the game, they decide to copy the Pakistanis 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 Pakistanis didn't
buy a ticket at all.
"How are you going to travel without a ticket?" says one
perplexed American.
"Watch and you'll see," answers a Pakistanis.
When they board the train the three Americans cram
into a bathroom and the three Pakistanis cram into
another bathroom nearby.
Once the train leaves the station, one of the
Pakistani leaves and walks over to the bathroom
where the Americans are hiding, knocks on the
door and says, "Ticket please."
