"How are three people going to travel on only one ticket?" asks Microsoft Employee.

"Watch and you'll see," answers the IBM Engineer.

They all board the train. The Microsoft Employees take their respective seats but all three IBM 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 Microsoft Employees saw this and agreed it was quite a clever idea. So after the conference, the Microsoft Employees decide to copy the IBM Engineers 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 IBM Engineers don't buy a ticket at all.

"How are you going to travel without a ticket?" says one perplexed Microsoft Employee.

"Watch and you'll see," answers a IBM Engineer.

When they board the train the t ffb hree Microsoft Employees cram into a restroom and the three IBM Engineers cram into another one nearby. The train departs. Shortly afterward, one of the IBM Engineers leaves his restroom and walks over to the restroom where the Microsoft Employees are hiding. He knocks on the door and says, "Ticket, please."
