Dimwit, the dopey dog, is a harried office worker and chain-smoking, gulping coffee and bottles of aspirin tablets does nothing to settle his jangling nerves. His doctor advises him to take up a relaxing , mild hobby. Dimwit tries woodworking, landscape painting and photography but all result in disasters that unnerve him even more. He shoots the doctor and finally finds a life that relaxes him...busting rocks in the fresh air of the prison yard.
