When Hawkeye is counting the reasons they are gathered at the end, number "1" is to celebrate Corporal Shaw's first night out. But when he mentions the second item is to dissolve Charles's non-marriage, he says "B" instead of "2". Either it was supposed to be "1" and "2", or "A" and "B", but Alan Alda got mixed up when giving his lines.
This is not correct. The lines were scripted to demonstrate that the participants in the party were already heavily intoxicated.
Hawkeye states, "All anyone knows for sure is hemorrhagic fever has two Hs, two Rs, and no cure." "Hemorrhagic fever" actually has three Rs.
The doctors ( with the exception of Major Winchester) constantly refer to the patients losing "salt" and the solution should have just a pinch of "salt". This is layman's terms for sodium chloride, and typically wouldn't be used by medical professionals.
