There just happened to be a lawyer convention and a plumber convention in Oregon at the same time. There was a party of three plumbers and three lawyers leaving California and taking the train to the conventions. As they were standing in line for tickets, the lawyers noticed that the plumbers only bought one ticket. The lawyers bought their three tickets and boarded the train but watched the plumbers to see how they were going to get by with only one ticket.
After boarding, the three plumbers squeezed into a restroom. Finally the porter came by and knocked on the door as he said, "Ticket please". The door cracked open and an arm reached out and gave the porter the ticket.
After the conventions, the lawyers decided to do the same thing so they only purchased one ticket. However they noticed the plumbers didn't purchase any tickets at all. They weren't too concerned though because -hey- they were saving some bucks right? Well, they all boarded the train and the lawyers packed into a tiny restroom. After a few minutes, one of the plumbers came by and knocked on the door saying, "Ticket please."
