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 three people going to travel on only
one ticket?" asks an accountant. "Watch and you'll see,"
answers an engineer.
They all board the train. The accountants take their
respective seats but all Three engineers cram into a restroom
and close the door behind them. Shortly after the train has
departed, the conductor comes around collecting 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 it and moves on.
The accountants saw this and agreed it was quite a clever
idea. So after the conference, the accountants decide to copy
the engineers 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 engineers buy no
tickets at all.
"How are you going to travel without a ticket?" says one
perplexed accountant. "Watch and you'll see," answers an
engineer.
When they board the train the three accountants cram into a
restroom and the three engineers cram into another one
nearby. The train departs. Shortly afterward, one of the
engineers leaves his restroom and walks over to the restroom
where the accountants are hiding. He knocks on the door and
says, "ticket please."
