I have a big bag of tricks I use to jumpstart my head when I'm in a writing drought. Reading the paper, making lists, pretending to stare out the window while I take a nap. . . Sometimes it takes a while for something to float up at you, or sometimes, as with this cartoon, they jump out and hit you between the eyes. "Content as a cow" combined with a bad sales graph pretty much writes itself. And I got to draw a cow! Win-win!
