Some lawyers were traveling to New York City to attend a conference. On the first scheduled day of the conference, they saw a group of teenagers while waiting in line to buy train tickets into the city.
When they reach the counter, the three lawyers each buy tickets and watch as the three teenagers buy only a single ticket. "How are three people going to travel on only one ticket?" asks a lawyer. "Watch and you'll see," answers a teenager.
They all board the train. The lawyers take their respective seats, but all three teenagers cram into a restroom and close the door behind them. Shortly after the train has departed, the conductor comes around collecting tickets. He sees that the restroom is occupied and knocks on the door saying, "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. After a minute or so the teens scramble for the seats. The lawyers see this and agree it was quite a clever idea.
So after the conference, the lawyers decide to copy the teenagers 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 same three teenagers are there too and they didn't buy any tickets. "How are you going to travel without a ticket?" says one perplexed lawyer. "Watch and you'll see," answers a teenager.
When they board the train the three lawyers quickly cram into a restroom and the three teens cram into another one nearby. The train departs. Shortly afterward, one of the teens carefully leaves his restroom and quickly walks over to the restroom where the lawyers are hiding. He knocks on the door and says, "Ticket, please."
