The last few minutes of this week's 'Running Man' saw the appearance of legendary idols Shinhwa! Appearing as pirates who stole all of the gold prizes earned through this week's competition, they were just as flustered as the cast themselves when they discovered that the gold had been cursed and replaced with useless scrap metal.

Now competing against the cast members to win back the cursed gold, next week's episode shows the idols versus the cast in an epic showdown of wits, strength, and agility!

Check out the preview below and don't forget to tune in to next week's 'Running Man'!
