North vs. South

They all board the train. The three Yankees take their respective seats but all three Southerners cram into a toilet together and close the door. Shortly after the train has departed, the conductor comes around collecting tickets. He knocks on the toilet door and says, "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.

The Yankees see this happen and agree it was quite a clever idea, so after the game, they decide to do the same thing on the return trip and save some money.

When they get to the station, they buy a single ticket for the return trip, but see, to their astonishment, that the three Southerners don't buy any ticket at all. "How are you going to travel without a ticket?" asks one perplexed Yankee. "Watch," answer the men from the South. When they board the train the three Northerners cram themselves into a toilet and the three Southerners cram into another toilet just down the way. Shortly after the train is on its way, one of the Southerners leaves their toilet and walks over to the toilet in which the Yankees are hiding. The Southerner knocks on their door and says, "Ticket please".
