It's easy! Just open a bunch of windows in a bunch of programs (make sure to have some with activity in them, like movies and web pages with animation). Now just press F9 F10 F11 F10 F9 F10 F11... and so on. Try Mary Had a Little Lamb, or Twinkle, Twinkle. Oh, the fun never stops! Macs are just the greatest. Let's see Windows do something as important as this! For advanced play, put your other hand on the mouse and to try to minimize and maximize windows. For special effects, set the desktop background to change picture every five seconds. What else?
