La-di-dum-de-dee . . . "Green Prairie"?

[Lucy]

What was that song that, I think, Ji-hae's mom was singing? I was a little feverish while watching the episode, but I could swear she was humming a song with those lyrics (something about "I'll build a house for me and my family on the green prairie") while talking about Ji-hae and her husband. Isn't it funny? I suppose that's where the title of that other show came from.

I was thinking the same thing! It must be a popular phrase or song?
