Although the 'couple race' format of this episode was nothing new, the guests selected to partner up with the cast members surely were. From rookie singer Kim Ye Rim to senior actor Park Sang Myun, to real-life couple Jo Jung Chi and Jung In, the couples ran the gamut.

The highlight, however, was the 'Monday Couple' duo, who took advantage of the format to snag the win for this episode!

In contrast to usual episodes, where the winner was awarded with a gold piece of some sort, this episode found the couples starting off with their own gold medallions, which they would have to keep -- or lose -- as the games progressed. After a gauntlet of missions, two couples had tied for the most amount of gold they carried, one of them being the Monday Couple.

To determine the final winner, each couple split up by themselves and asked to write down their choice between 'gold' and 'couple' on a sheet of paper. If they both specified 'gold', their winnings would be distributed among the remainder of the cast. If one of them wrote 'couple' and the other wrote 'gold', they would be able to keep the winnings. However, if both of them wrote 'couple', they would win twice the amount of gold they carried!

With the rest of the cast members waiting in anticipation, they both revealed their answers. Both Gary and Song Ji Hyo had written down 'couple', granting them the best conclusion possible!

Struck in the heat of the moment, guest Kim Kwang Gyu chanted, "Kiss! Kiss! Kiss!", ending the episode on a definite high note.
