Popular joke, I read it years ago. I found it again. It's hilarious. "Apple vs. Microsoft" Three Microsoft engineers and three Apple employees are traveling by train to a computer conference. At the station, the three Microsoft engineers each buy tickets and watch as the three Apple employees buy only a single ticket.__"How are three people going to travel on only one ticket?" asks a Microsoft engineer.__"Watch and you'll see," answers the Apple employee.__They all board the train. The Microsoft engineers take their respective seats, but all three Apple employees cram into a restroom and close the door behind them. Shortly after the train has departed, the conductor comes around collecting tickets. He knocks on the restroom door and says, "Ticket, please."__The door opens just a crack and a single arm emerges with a ticket in hand. The conductor takes the ticket and moves on.__The Microsoft engineers saw this and agreed it was quite a clever idea. So after the conference, the Microsoft engineers decide to do the same 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 Apple employees don't buy any ticket, at all.__"How are you going to travel without a ticket?" asks one perplexed Microsoft engineer.__"Watch and you'll see," answers an Apple employee.__When they board the train the three Microsoft engineers cram into a restroom and the three Apple employees cram into another one nearby. The train departs.__Shortly afterward, one of the Apple employees leaves his restroom and walks over to the restroom where the Microsoft engineers are hiding. He knocks on the door and says, "Ticket, please..."
