What A Do Theater will present an excerpt from its "Cheaper by the Dozen" production. The family comedy is loosely based on the book about time and motion study by efficiency experts Frank Bunker Gilbreth and Lillian Moller Gilbreth. The Gilbreths' oldest daughter, Anne, is in high school and mortified when her father decides to apply his unorthodox methods to the family of 12 children. The results are terribly embarrassing, funny, and extremely effective. What A Do Theater will perform "Cheaper by the Dozen" at its theater in Springfield throughout March.
