Jed gets invited to the opening of Drysdale’s new Commerce Bank building. Granny thinks that he will actually be building the bank. Jed attends the party and meets two of Drysdale friends, who think he is a market wizard. They listen to Jed talk and take tips from him, actually just Jed talking about food. When Jed is told he is helping to build the bank, he and Jethro head home to get tools and pick up Elly and Granny to help out. When they get there, they cause a bit of a disturbance and misunderstand what is going on. They think they have to help build the “barn.” And when everybody leaves, they feel they should do it themselves. The next day, Jane and Drysdale look out the window and see something in the space where the bank will be. The Clampetts built a very small New Commerce Bank building over night.
