Three lawyers and three accountants were traveling by train to a conference. At the station, the three accountants each bought tickets and watched as the three lawyers bought only a single ticket.
"How are three people going to travel on only one ticket?" asked an accountant.
"Watch and you shall see," answered one of the lawyers.
They all boarded the train. The accountants took their seats, but all three lawyers crammed into the tiny restroom and closed the door behind them.
Shortly after the train departed, the conductor came around collecting tickets. He knocked on the restroom door and said, "Ticket please."
The door opened just a crack, and a single arm appeared with a ticket in hand. The conductor took it and moved on.
The accountants saw this and agreed it was quite a clever idea.
So, after the conference they decided to copy the lawyers on the return trip and save some money. When they got to the station they bought a single ticket for the return trip. To their astonishment, the lawyers didn't buy any tickets at all.
"How are you going to travel without a ticket?", asked one perplexed accountant.
"Watch and you'll see," answered a lawyer.
When they boarded the train, the three accountants squeezed into a restroom, and the three lawyers squeezed into another one nearby.
The train departed. Shortly afterward, one of the lawyers left the restroom and walked over to the restroom where the accountants were hiding. He knocked on the door and said, "Ticket, please."
