After a young boy is operated on and Radar can't find his parents, he stays at the 4077th for a while.
It was touching to see how a young boy could have such an impact on just about everyone in the camp. (especially Trapper)
After the boy wandered into a minefield and trapper had to zig zag his way through it to get to him his mum showed up and took her son away.
This minefield scene was pretty funny. (a lot like the one where Trapper and Hawkeye had to difuse a bomb that landed in the compound) They were both serious situations but on both occasions Henry's imcompetence to read the instructions provided great laughs.
This was a more serious out of character episode, but the quality was still there.
