Book excerpt: Deep in the Heart of Tuna is a "Best Of" Tuna show that follows the story of Bertha Bumiller and her beautifully dysfunctional family. Tuna, Texas is the third-smallest town in the state, where the Lion's Club is too liberal and Patsy Cline never dies. The eclectic band of citizens that make up this town are portrayed by only two performers, making this satire on life in rural America even more powerful as they depict all of the inhabitants of Tuna- men, women, children, and animals. -- Publisher website.
