McHale decides that what Ensign Parker really needs is a girl friend. He convinces Parker that he is suffering from an advanced case of battle fatigue so that he can be sent to the hospital, where McHale hopes that he will find Nurse Casey Brown to his liking.

When McHale and his men are assigned the duty of averting a Japanese attack on a US convoy, they use the soundtracks of movies starring John Wayne, Humphrey Bogart, and Errol Flynn to confuse the enemies.

Mchale decides for Christmas he and the crew of PT-73 will pay a visit to the Sister Monique and the children dressed up in a Santa Claus outfit and elf outfits. Mchale would parachute from a plane first and meet the kids and PT-73 would follow a little while after. Mchale jumps in his Santa outfit but when he lands he finds the island was overtaken by Japanese and was captured. Mchale as usual cons he's why through the itterogation and he claims that a new secret weapon is on it's way, just then PT-73 arrives singing Christmas carrols and dressed in elf outfits. The Japanese commander becomes scared fearing that this was some kind new of physcological warfare and he surrenders.

A U.S. Congresswoman comes to Taratupa, to find a War Hero to take on a Stateside War Bond tour, and Parker and the boys help McHale to get chosen for the job, thinking that they will be going along.

Trouble ensues, when Parker inadvertently invites three of the 73 Crew's Mothers – Including his own – To visit Taratupa for Mother's Day.
