Many of the cartoons from the Harvard Business Review are online free (most the articles are pay-to-read). The October issue has a cartoon that cubicle dwellers understand. I haven't figured out how to go directly to arbitrary HBR monthly comics, but here is the link to October's, and you can see more by using the Browse Issue function on the right, pick the month you want, and then click Cartoons.
Besides the cube cartoon, farther down the page is a good one for anyone going to too many meetings.
