그의 농담에 웃음이 났다.
geu-ui nong-dam-e us-eum-i nass-da., geu ui nong dam e us eum i nass da.
Because laughter naturally emerged from emotion, '웃음이 났다' is appropriate.
그는 농담에 웃었다.
geu-neun nong-dam-e us-eoss-da., geu neun nong dam e us eoss da.
Since he intentionally laughed, '웃었다' is correct.
그는 웃음이 났다.
geu-neun us-eum-i nass-da., geu neun us eum i nass da.
'웃음이 났다' is awkward with a human subject like '그는'; use '그는 웃었다' instead.
상황이 너무 웃었다.
sang-hwang-i neo-mu us-eoss-da., sang hwang i neo mu us eoss da.
Situations cannot laugh, so '웃었다' is incorrect; use '웃음이 났다' for situations.
그 상황에 웃음이 났다.
geu sang-hwang-e us-eum-i nass-da., geu sang hwang e us eum i nass da.
It's natural to say a situation caused laughter.

na-neun us-eum-i nass-da., na neun us eum i nass da.
With a human subject, use '웃었다'; '웃음이 났다' suits emotions or situations.

geu-nyeo-neun us-eoss-da., geu nyeo neun us eoss da.
Correct for intentional, direct laughter.
그녀는 웃음이 났다.
