Coots are a common term applied to feisty and ornery older people. Avengers are people who don't take guff from others and get back at people who try to abuse them. Together, these words describe our cartoon characters perfectly.

From the moment our cartoons began appearing in local newspapers, and interviews on Public Radio and elsewhere were broadcast, the creators of these cartoons were bombarded with comments from people who said things like "Right. That's me. That's what I think and that's what I do."
