As the Ricardos and the Mertzes prepare for their ocean voyage to Europe, Fred Mertz (William Frawley) struggles gamely but vainly to overcome his chronic seasickness. Lucy (Lucille Ball) suggests that Fred take a trial run on the Staten Island Ferry, and that he fortify himself with seasickness pills. Unfortunately, it is Lucy who develops a bad case of mal de mer -- and worse still, the pills make her extremely drowsy, just at the moment that she must apply for her passport. ~ Hal Erickson, Rovi
