My wife's cousin owns a dairy farm in Germany and only uses homeopathic medicines on the cows. When I stifled a chuckle, he indignantly pointed out that not only does it appear to work for his cows, it isn't as if the cows can understand him, nor know that they are being treated.

However much I have my doubts about homeopathy, his cows seemed healthy and weren't being pumped full of antibiotics; hence I saw it as a good thing.
