Q: How many Apple employees does it take to screw in a light bulb?
A: 121. 100 engineers to design a new eyeball which can operate in complete darkness, making light bulbs obsolete, 20 marketing people to pursuade the world that the new eyeball is actually a kind of light bulb with a new kind of socket which can also take Microsoft light bulbs, and 1 manager to get confused by the difference between an eyeball and a light bulb, and cancel the project because the new eyeballs don't fit standard light sockets.
