Traveling by train

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."
