Pai, a severely injured North Korean POW is taking up a valuable bed in Post-Op and Pai requires AB- blood, the rarest type of blood in both Caucasians and Asians. So, naturally Frank wants to ship off Pai to the POW section. Pai is Hawkeye's patient; and Hawkeye will not release Pai. But, the whole 4077 Post-Op situation is dire and Henry takes Frank's side; and the guys tell Henry he is turning into a real Army clown. (Cue M*A*S*H, the movie.) Ruefully, Henry has to acknowledge their censure and he tells Trapper and Hawkeye to care for Pai for as long as they want, but to keep Frank (aka Mrs. Henry Blake in Army drag) OFF Henry's back. With Pai a guest I n The Swamp in Hawkeye's cot, the next issue is blood: Radar scours 4077 personnel records to find their rare blood donor. Poor Frank has a dream he is a giant soda with a big straw sticking out of him!

Did You Know?


In this episode we learn Frank Burns has AB- blood. See more »


Henry states that he can't give AB- blood to the POW in case "one of our kids needs it," so Trapper and Hawkeye look through the personnel records to find a donor with AB- blood. People with AB- blood can receive blood from donors with AB- blood, obviously, but can also receive A-, B-, and O- blood as well. AB- is the rarest blood type, and it would've been easier to find a donor with any compatible blood type. See more »


Maj. Margaret 'Hot Lips' Houlihan: [while struggling to get out of the surgical gown and handcuffs that Trapper used to tie her to Frank] Colonel! Look at us!
Lt. Col. Henry Blake: It does look pretty silly without the music.

Much Ado About Nothing
22 February 2015 | by HitchcocSee all my reviews

Sometimes the series crosses over into the really hard to believe. In this one, Trapper and Hawkeye take a pint of blood from Frank while he sleeps (I guess that's possible) and give it to a North Korean patient. It turns out that the Korean has a strain of hepatitis. While he may have already had it, it was diagnosed after the transfusion which means it could have come from Frank and Frank should not be operating on patients. But how do you confirm it and keep Frank out of the operating room without telling him about the blood? Also, how do you keep him away from Margaret Houlihan, with whom he has a constant liaisons. The scene where they get Frank to "give" a urine sample is hilarious. Of course, this show was continuously outrageous so we can cut them some slack. That said, these medical men are so moral when it comes to patients but seem to throw it aside at times when it comes to adversaries.
