Ahhh memories.
Seeing this thread I had a flash back to the Douglas Adam's Hitch Hiker's books.
The scene:
A group of middle managers and interior designers expelled from a distant planet who crash landed on earth 60,000 years ago, all siting around trying to solve the problems of their new habitation.
Arthur Dent berrates them for sitting there for three days and they haven't even invented the wheel.
They retort that they have invented the wheel, they just cant make any progress until they determine what colour it should be.
