During SBS's 'Running Man: Hip Hop Special', Dynamic Duo member Choiza ripped their pants during a road challenge mission. 'Running Man' member Haha jokingly told Choiza, "Ripping your pants was a good thing. You're doing a good job getting lots of air time," making everyone laugh. After coming out of the army, it's been a while since Dynamic Duo has appeared on variety shows, so Gaeko replied,�"Filming Running Man was harder than receiving training from the army." Simon D, who was also a guest on this episode,�added, "Appearing on the show I personally enjoy watching was fun to record." Dynamic Duo, Simon D, and the Tiger JK Yoon Mirae couple appeared on this episode. The episode will air on September 4, 5:10pm KST.
