Three engineers and three accountants are traveling by train to a conference. At the station, the three accountants each buy tickets and watch as the three engineers buy only a single ticket.
"How are you going to travel with only one ticket?" asks an accountant.
"Watch and you'll see," answers one of the engineers.
They all board the train, and the accountants take their seats, while the three engineers cram into a restroom and close the door behind them.
Shortly after the train departs, the conductor comes around to collect tickets. He knocks on the restroom door and says, "Ticket, please." The door opens just a crack, and a single arm emerges with a ticket in hand. The conductor takes the ticket and moves on.
The accountants are impressed by this clever trick. On the way back from the conference, they decide to try the same tactic and save some money. When they get to the station, they buy a single ticket for the return trip.
To their astonishment, the engineers don't buy a ticket at all.
"How are you going to travel without a ticket?" asks one of the accountants.
"Watch and you'll see," answers an engineer.
They all board the train. The three accountants cram into one restroom, and the three engineers cram into another restroom nearby.
Shortly after the train departs, one of the engineers leaves his restroom, walks over to the restroom where the accountants are hiding, knocks on the door, and says, "Ticket, please."
