Programming Joke

A group of programmers and a group of DumbUsers found themselves going
to a conference on the same train. The DumbUsers had tickets but the
programmers had only one ticket between them, which was a source of
ridicule.

When one of the programmers yelled "The conductor is coming", they all
ran into a rest room. The conductor took tickets from the DumbUsers,
then knocked on the rest room door and announced "Ticket Please". A
single ticket was pushed under the door.

On the return trip, DumbUsers decided to play the same trick. They
bought one ticket for the group. This time they noticed programmers
had no tickets, which was another source of ridicule. When someone
yelled "The conductor is coming", all the DumbUsers ran into one rest
room and programmers ran into a second.

Before the conductor entered the car, a programmer exited from his
rest room, went to the other, knocked on the door, and announced in a
loud officious voice "Ticket Please".
