 Out-of-work vaudeville team Marvin and Marita offer Granny free in-home dance lessons in a scheme to get a foot in the door and hopefully sell the Clampetts additional lessons. Believing the schemers have lost their lease on their dance school, Jed and Granny generously offer to have Marvin and Marita bring their other [non-existent] students to the Clampett mansion. This episode offers a couple of good jokes, a wink and a nod to the brother and sister vaudeville dance team of Buddy and Vilma Ebsen, and ends with Jed s tap routine at the Bankers Convention Variety Show.
