While boarding the USS Constitution on the first leg of the Ricardos' and the Mertzes' trip to Europe, Lucy (Lucille Ball) impulsively races down the gangplank to bid one last goodbye to Little Ricky. Unfortunately, she gets her dress caught on a bicycle chain and is unable to return to the ship, which sails without her. Desperate to be reunited with her husband and friends on the deck of the Constitution, Lucy ends up placing her life in the hands of a friendly helicopter pilot. Watch for future Chico and the Man star Jack Albertson in the small role of a helicopter dispatcher. ~ Hal Erickson, Rovi
