Uncle Charley's romantic tales of adventure captivates Ernie's teacher. The pretty, middle-aged lady is fascinated by the old boy's partially-true tales of his exciting life on the high seas. Soon the ex-seacook is aghast to learn she has given up her teaching job and he is further torn when she explains her savings will buy them both a one-way ticket to Pango-Pango and asks him to marry her before they leave.

Other fathers help their sons in a school science fair, but Steve tells Ernie he's on his own. Soon his project turns to disaster when his very crudely built electric clock absolutely refuses to run. After vainly pleading that most of his classmates are getting parental help, on the day of the fair, Ernie must be forced to go to school.
