He does mention this:
It's horse-and-sparrow journalism. The horse blazes the trail and eats the hay. The sparrows feed on what the horse leaves behind in steamy piles on the road.
UPDATE: I should have known better. I had just received the email from Town Hall mentioning this about 2:30AM, when even Glenn Reynolds sleeps. It looked like it was dated on the 27th. But this originally was published on the 24th in the WashTimes. Maybe next time...
I must say, I like his characterization of what the horses of the media produce. Especially the Horse - take it away, folks.
