Train Tickets & the Engineers

[jhhop]

Three Apple engineers and three Microsoft employees are
traveling by train to a conference. At the station, the three
Microsoft employees each buy tickets and watch as the three
Apple engineers buy only a single ticket.

"How are three people going to travel on only one ticket?" asks
a Microsoft employee. "Watch and you'll see," answers the Apple
engineer. They all board the train. The Microsoft employees take
their respective seats but all three Apple engineers cram into a
rest room and close the door behind them.

Shortly after the train has departed, the conductor comes around
collecting tickets. He knocks on the rest room 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
Microsoft employees saw this and agreed it was quite a clever
idea.

So after the conference, the Microsoft employees decide to copy
the Apple 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 Apple engineers don't buy a
ticket at all. "How are you going to travel without a ticket?"
asks one perplexed Microsoft employee. "Watch and you'll see,"
answers an Apple engineer.

When they board the train the three Microsoft employees cram
into a rest room and the three Apple engineers cram into another
one nearby. The train departs. Shortly afterward, one of the
Apple engineers leaves his rest room and walks over to the rest
room where the Microsoft employees are hiding.

He knocks on the door and says, "Ticket, please".
