Cartoonist John Callahan. Callahan comes up with comics that are both funny and often offensive (a typical example: an obese man stands with his obese son in front of the refrigerator, saying "Son, someday all of this will be yours."). Callahan often pokes fun at alcoholics and the disabled, something he's qualified to do. Callahan was a alcoholic for many years, and he was left a quadriplegic after a drunk driving accident.
Callahan was paralyzed in a drunk driving accident. Since then, he's become comic strip artist whose irreverent cartoons focus on the experiences of the disabled. Callahan's new memoir is called Don't Worry, He Won't Get Far on Foot.
