this episode of Judge John Hodgman. You need to hear it. Really. Cow.
The Cow Beef
Ted brings this case against his father Paul, who has become obsessed with cows. Ted argues that his father's cow collection and his inclination to randomly say the word cow, among other issues, indicate the need to tamp down the cow-talk. Paul argues that his obsession is merited, because "cows are our most important animal friends."
