Goof: As the helicopter takes Kim and Trapper to safety, the area around them is in early morning fog; no sunlight no shadows, however, shots of the other people watching are clear and their shadows are very clear to see.
Goof: Kim is sitting on a good size rock in the mine field, however when Trapper pulls the kid out by helicopter, the rock is gone.
Henry: (working Trapper through the minefield) Take a step and a half to your right, and you should be in downtown Berlin.
Hawkeye: Berlin? (takes the map): This is a WWII surplus map!
Margaret: You happy, Frank?
Frank: Happy? I'm with you, 10,000 miles from home in war-torn Korea I'm the happiest man in the world.
Margaret: So am I.
(Hawkeye reads Trapper's letter to his wife)
Hawkeye: It's beautiful.
Trapper: Okay, it's beautiful, but is it a mistake?
Hawkeye: How can you make a mistake giving a kid his life? You're all daddy.
(Kim is in the minefield and Trapper starts to run in)
Hawkeye: Hold it!
Trapper: I gotta get the kid out of there!
Hawkeye: Do you want to make him an orphan again?!
(Hawkeye looks for maps of the minefield)
Hawkeye: Why aren't they under M?
Radar: Because they're under B. For "Boom."
(Trapper makes a balloon out of a rubber glove)
Hawkeye: Looks like a pregnant bagpipe!
Trapper: Do bagpipes get pregnant?
Hawkeye: Sure they do, right after they make those funny noises!
Hawkeye: (to a sleeping Blake) Goodnight sweet prince!
