Jong Kook's best friend, Cha Tae Hyun, joins us for this week's Congratulatory Delegation with Kook's Patience race to celebrate Jong Kook's marriage. But for someone who cringes at even a birthday song, today's over-the-top party is pure torture. Through missions, the members will try to remove corny and fussy celebration items, while Jong Kook collects chance cards to his advantage. Every chance card he uses adds another penalty member. Will Jong Kook endure the embarrassment, or will the celebration spiral out of control?
