To get away from Zelda, Dobie (and Maynard) stow away on a ship heading for South America. Little do they realize that Zelda has also stayed on board.

In Mr. Pomfritt's class, Dobie learns that married people are better off, so he decides to marry Zelda. Herbert and Maynard, each for their own reasons, are not too happy about this, and even Zelda is having second thoughts.
