I tend to be pretty skeptical of the the whole "cost of a gallon of milk" question (mostly because, despite the fact that I buy milk at least once a week, I couldn't answer the question myself), so I've been glad to see that a lot of the response to Giuliani's recent bungling has been along those same lines. The best response I've seen, though, is definitely this one, in which Michael Tomasky suggests replacing the fairly arbitrary "price of milk" with a list of ten numbers that really would demonstrate political in-touchitude.
