Three Inter Fans and three Juventus Fans are travelling by train.
At the station, the three Inter Fans each buy tickets and watch as the three Juventus Fans buy only a single ticket.
"How are three people going to travel on only one ticket?" asked an Inter Fan.
"Watch" answers a scouser.
They all board the train. The Inter Fans take their respective seats but all three Juventus Fans cram into the toilet and close the door behind them.
Shortly after the train departs, 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 Inter Fans saw this and agreed it was quite a clever idea. So, on the return trip, the Inter Fans decide to copy the Juventus Fans 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 Juventus Fans don't buy a ticket at all.
"How are you going to travel without a ticket," asks one perplexed Inter Fan.
"Watch" says an Juventus fan.
When they board the train the three Inter Fans cram into a toilet and the three Juventus Fans cram into another one nearby. The train departs. Shortly afterward, one of the Juventus Fans leaves his toilet and walks over to the toilet where the Inter Fans are hiding. He knocks on the door and says, "Ticket, please".
