The kids need fifteen dollars. Lucy is broke, so Harry pays her to do some extra tasks, which includes taking an heirloom ring to be engraved.
Lucy goes through havoc when she thinks she loses the antique ring in wet cement. She disguises herself as a cement worker wielding a jackhammer and ends up being dumped over the head with cement.
Special Notes: Paul Winchell plays two characters in this episode, the French knife thrower and the little old jeweler. In the office scene, Lucy and Harry are looking for the Morton contract. Morton is Lucy's married name, having wed comedian Gary Morton in 1961.
