Trust me. It's not as easy as it looks.
Well, thinking positively, don't have to learn a lot of Korean... just some common phrases:
"YOU! Pick the rice in the pattys over there..."
"Where do you want me to hang up the portrait of our Dear Leader?"
Personally, I find “yes, yaobo” (honey) to be the most useful Korean phrase.
But I think that applies to any husbands anywhere regardless of language ;-)
