On a trip to the extremely rundown Springfield Mall, Homer happens across the Time–Life Carpenter's Library, and Marge encourages him to buy them. Homer's interest in carpentry fades, and Marge decides to use them herself to fix up the house. She begins to learn more about carpentry and Lisa suggests to Marge that she try to earn some money as a handywoman, thus opening up "Simpsons Carpentry". However, potential clientsSuperintendent Chalmers and Krusty the Clown turn her down, dismissing the idea of a female carpenter. Commenting on how people expect carpenters to be male, Marge develops a plan: she uses Homer as a front to the customers, while Marge, hiding in a red tool chest, does all of the work as Homer rests in the toolbox, and switches back when the customers come to check on Homer's work.
