During the show, the members of 'Running Man' were obligated to finish their own missions to win the whole game.�





For one of the missions, Kim Jong Kook had to get slapped by a female celebrity�born in the 90s. To complete this, he met up with Eunji who was born in 1993. As soon as they met up, Kim Jong Kook proposed to play a game of rock, paper, scissors. He won 2 times in a row which made him flustered as he needed to lose in order to get slapped for the mission. On his last try, he finally lost and received a slap on the forehead he probably won't forget for a long time.�
