things I've tried to convince my wife of recently:

That Dyson Vacuums are manufactured in Zimbabwe, and the proceeds of purchasing one would go directly into the murderous hands of Robert Mugabe and his goons, and thus finance the continued oppression of citizens in that corner of the world. They are, therefore, 'Blood Vacuums.'

She on the other hand, would never part with ours. Never. Regardless of who it hurts.
