IF OPERATING SYSTEMS WERE AIRLINES..... DOS AIR.. Passengers walk out onto the runway, grab hold of the plane, push it until it gets in the air, hop on, then jump off when it hits the ground. They grab the plane again, push it back into the air, hop on, jump off.. GEM AIRLINES.. The same as DOS, but with more leg room to push. MAC AIRWAYS.. The cashiers, flight attendants, captains, baggage handlers and pilots all look the same, act the same and talk the same. When you ask them questions about the flight, they reply that you don't need to know, don't want to know and would you please return to your seat and watch the movie. WINDOWS AIRLINE.. The terminal is neat and clean, the attendants courteous, the pilots capable. The fleet of Lear jets the carrier operates is immense. Your jet takes off without a hitch, pushes above the clouds and, at 20,000 feet, explodes without warning. OS/2 SKYWAYS.. To get on board, you have to have your ticket stamped 10 different times by standing in 10 different lines; then you have to fill out a form that states how you want your seating arrangement to be - whether it should have the look and feel of an ocean liner, a passenger train, or a bus. If you are successful in getting on board and getting off the ground, you have a wonderful, enjoyable trip - except for times when the rudder and flaps freeze shut, in which case you have time to say your prayers and get your personal things in order before you crash. FLY WINDOWS NT.. Passengers carry their seats out onto the tarmac and place them on the outline of a plane. They sit down, flap their arms, and make jet swooshing sounds as if they are flying. UNIX EXPRESS.. Passengers bring a piece of the plane and a box of tools with them to the airport. They gather on the tarmac, arguing about what kind of plane they want to build. The passengers split into groups and build several different aircraft but give them all the same name. Only some passengers reach their destinations, but ALL of them believe they arrived.
