Three engineers and three lawyers are taking a trip together via train. The lawyers buy one ticket per person, but the engineers only buy one total. ""How are you going to get away with that?"" the lawyers ask. ""Watch and learn,"" say the engineers. So they all board the train, and when the conductor begins collecting tickets, the three engineers cram themselves into a bathroom. The conductor knocks on the door and says, ""Ticket, please."" A single hand sticks out and gives him the ticket. In this way, all three engineers manage to ride the train on one ticket. The lawyers are clearly impressed. On the return trip, they only buy one ticket for all three of them. The engineers, however, don't buy any at all. ""How are you going to get away with that?"" the lawyers ask. ""Watch and learn,"" say the engineers. On the train home, the lawyers cram themselves into one of the bathrooms. An engineer walks over, knocks on the door, and says, ""Ticket, please.""
