It'd be easier for someone who actually watches Scrubs... but in this episode, one of the characters imagines himself serving in Asia. And they translated "Up Where We Belong" into, I think it's Vietnamese. Sorry, the song happens 5:41min into the video and only lasts like 10 seconds. But is it actually Vietnamese? Could be Thai... not sure.

I am pretty sure it's not Vietnamese.

is it just made up? lol.

A failed attempt to sing in Vietnamese when a singer does not have the commanding pronounciation of the Vietnamese language.
The song started out as....chuyện tình đôi ta...then I completely lost the rest...Vietnamese language is very tonal. Sound close enough doesn't cut it.
