How many Audiofools does it take to change a light bulb?

Not many but they take bloody forever! Too much debate about what material the steps are to be made from, building tweaky suction cups to hold the bulb without touching the glass, should we mount the steps on castors? Hold the bulb still and rotate the steps? Should the castors have brass bearings for efficient transfer of energy?..... whatever - get a woman to do it. Or a vertically challenged guy on a trampoline, that would be funnier
