Best episode yet -- laughter and excitement!

I have been WAITING for the episode that explains the title! This episode was written perfectly to lead up to why Han Guil has a "secret life" that we had no clue about before. It was subtle and graceful and not an obvious, in-your-face announcement and somehow that made it all the more thrilling. Another thing I loved about this episode is that not only was Han Guil cracking me up but Director Do began to, as well!
