A salesman comes to the farm and tells the farmer he's got the ultimate solution to his labor troubles. Chrome robots. They work all day and night, don't need to be paid, and don't steal
half your crop like the Mexicans do.
The farmer thinks, heck, he's got nothing to lose, so he buys them.
Just as the salesman promised, the robots were harvesting his crops in record time. Unfortunately, the next day, a Highway Patrolman knocks on his door and tells him that the sun reflecting off the robots is blinding motorists and he needs to do something about it.
So that night, he paints the robots black.
The next day, half of them don't come in to work.
