Sun even produced a TV commercial in which an arrow that presumably had all of Sun's wood behind it whooshed through the air and hit the bull's eye of a target. (Nobody at Sun ever knew what the target was, but by golly they all knew which arrow to put their wood behind.)

Sun touts an "all the wood behind one arrow" slogan, meant to describe a company focused on one goal - workstations. As an April Fool's joke in 1990, Sun employees built a 60-foot-long arrow in McNealy's office with the point going out the window.
