Plot synopsisEdit

Margaret suspects she's pregnant, but in order to be sure, a pregnancy test must be performed, but in order for the test to be done, they need the ovaries of Radar's female rabbit Fluffy; meanwhile, a disgruntled patient holds Charles hostage until he's allowed to be sent home to Ohio.

Full episode summaryEdit

During a session in O.R., everyone seems to notice how snippy Margaret seems to be. She gets frustrated at every joke Hawkeye utters, and puts Nurse Bell on report for a petty mistake (even going as far as "baiting" her to do so).

After O.R., Hawkeye asks her what's the problem, and after some cajoling she admits she's irritated because...she might be pregnant.

Hawkeye is ecstatic, but Margaret is not: she and Donald Penobscott are not exactly getting along, and if she is pregnant, her whole Army career is, as she puts it, "kaput." But she's not positive she's pregnant, so Hawkeye helps her go about getting a test.

Meanwhile, a patient of B.J.'s, Lt. Martinson (Charles Frank) is furious over the idea of being sent back into battle. Because of his education, he was made an automatic Lieutenant, put in charge of other men. When some of them were killed due to his lack of experience, he flat out refuses to go back into combat. B.J. tries to console him, but Martinson will accept nothing less than being relieved of his command.

Hawkeye and Margaret turn to Col. Potter and tell him the news, and he is equally happy. They decide a pregnancy test is the next step, so they turn to the owner of the nearest rabbit they can find...Radar.

But when Radar is told that his beloved rabbit Fluffy has to die during the procedure, he is horrified, refuses, and storms out.

Hawkeye catches up with Radar, who it seems has let Fluffy free from her cage. Radar asks can't Hawkeye just remove the rabbit's ovaries (the part of the rabbit they test)? Hawkeye says it's possible, but since Fluffy is gone, what's the point?

At that point, Radar produces Fluffy out of his jacket, tentatively handing her over to Hawkeye, who promises to care for her as best he can.

While Hawkeye and Margaret perform the surgery, Lt. Martinson gets angrier and angrier at B.J. Winchester tries to relate to him, Ivy Leaguer to Ivy Leaguer, but that doesn't work, either. Martinson then pulls a gun and takes Winchester hostage, demanding a chopper home.

This stand-off crosses over into the O.R., where Hawkeye and Margaret have finished the operation on Fluffy and are about to perform the pregnancy test. But Martinson demands they all leave. Klinger, upon hearing Martinson wants a flight back to Ohio, volunteers to replace Winchester as a hostage.

Instead of being scared, Klinger is downright gung-ho about their prospects, but Martinson, weak from his wound and a lack of sleep, can barely stand. In fact, he passes out just as the chopper arrives, dashing Klinger's hopes of freedom.

Later, Hawkeye and Margaret do the pregnancy test, and it's negative. Margaret is happy, but Hawkeye admits he's a little disappointed. Margaret then pauses, and admits, "So am I."


  • M*A*S*H enters a new and permanent timeslot on CBS with this episode: Mondays at 9:00PM.
  • When the Colonel, Margaret, and Hawkeye are asking Radar to use his rabbit for the pregnancy test, he starts to balk, and Margaret grabs a bottle of what appears to be vodka and pours herself a drink. If she thinks she's pregnant, she shouldn't be drinking.
