two engineers got on a train with only one ticket. the accountants that were with them were confused, and asked how they thought they would get away with it. the engineers just laughed and told the accountants to watch.
when the conductor came thru to get tickets, the engineers crowded into the bathroom. when the conductor knocked on the door, on slipped his hand outside with the ticket.
the accountants thought this was a wonderful idea and decided to try themselves on the way back. but much to their surprise, the engineers didn't even bother to buy one ticket.
when the conductor started to come thru, the accountants crammed into one bathroom and he engineers into another. a minute later, one of the engineers knocked on the door where the accountants were and said "ticket please."
Oh thank you. I couldn't remember the details. Hilarious!
