Factory workers

In a small town in the US, there is a rather sizable factory that hires only married men. Concerned about this, a local woman called on the manager and asked him, "Why is it you limit your employees to married men? Is it because you think women are weak, dumb, cantankerous..or what?" "Not at all, Ma'am," the manager replied. "It is because our employees are used to obeying orders, are accustomed to being shoved around, know how to keep their mouths shut and don't pout when I yell at them."
