Three lawyers and three engineers were traveling by train to the same meeting. At the station, the lawyers each buy a ticket but the engineers buy just one. When asked why, the engineers coyly said "You'll see."

They all board the train, the lawyers taking seats, but the three engineers all crowding into the bathroom. After the train has left, the conductor comes around and takes the lawyers tickets and knocks on the bathroom door and says, "Ticket Please." An arm stretches out from the bathroom and the
conductor takes the proffered¹ ticket. The lawyers were very impressed.

On the return trip, the lawyers proposed to emulate² the gearheads and bought only one ticket. To their amazement³, the engineers bought no ticket at all. When asked, the engineers said, "You'll see."

All board the train and the lawyers and engineers cram⁴ into separate bathrooms to await the conductor. After a few minutes,
one of the gearheads emerges from the bathroom, goes over to the lawyers' bathroom, knocks on the door and says: "Ticket
please."
