Irritated that the 4077th is planning a "surprise" birthday party for him, Hawkeye aids a wounded surgeon at the front and habitually disagrees with wisecracking medical advisor Dr. Anthony Borelli. Constant interruptions prevent Klinger from frosting a cake in Hawkeye's honor.
Pierce is upset by the fact that civilian doctors are making a lot of money off the war, and decides to bill the army for all his work. Meanwhile, Winchester is reluctantly showing 3 Korean doctors American medical techniques, putting them down all the while, until he is on the receiving end of their expertise.
To fight an ongoing infection in the O.R., the staff decides to remove the old wood floor and make a concrete one. The surgeons do the menial labor while Klinger acts as foreman (he knows cement and it's not that hard); while an Italian soldier falls head-over-heels for Margaret.
It's Christmas time again. The surgeons and staff are throwing a Christmas party in the mess tent, and the children from the local orphanage are coming to join in the fun. B.J. donates a box of fudge from Peg and Charles donates some smoked oysters. Everybody in camp thinks Charles is a Scrooge, but, under the cover of darkness that night, Charles generously and anonymously donates packages of chocolate bars from home to the orphanage. The Christmas party takes off without a hitch. Colonel Potter dresses as Santa Claus and the children are having fun, but Hawkeye, B.J...
As the year 1950 comes to a close, the 4077th staff and surgeons hope 1951 is "a damn sight better" and hopefully they'll be going home. The year 1951 is not uneventful: Klinger makes a bet on a baseball team Charles is sure will lose, Hawkeye and B.J. build a kidney machine, Margaret knits a scarf which soon becomes a bed sheet, and Father Mulcahy plants a garden. By the time New Year's Eve rolls around again, they all hope 1952 will be "a damn sight better" and that they will be returning home.
