 Lou Costello plays a country bumpkin vacuum-cleaner salesman, working for the company run by the crooked Bud Abbott. To try to keep him under his thumb, Abbott convinces Costello that he s a crackerjack salesman. This comedy is somewhat like "The Time of Their Lives," in that Abbott and Costello don t have much screen time together and there are very few vaudeville bits woven into the plot.
