Korea's longest-running variety-dols Shinhwa greeted the cast of 'Running Man' in full pirate garb on the latest episode!

The cast were surprised by their appearance at the tail end of this week's episode. They had spent the previous few hours battling each other to secure the highest ranking within the cast members, for which they had received an appropriate amount of gold in return. Boarding a ship to deposit their gold, they found themselves robbed, bound, and gagged and left to stew until morning.

Upon morning, the cast found themselves captives of the Shinhwa pirate gang, but when they found out that the gold was missing -- replaced by worthless scrap -- they set out to recover the missing gold for themselves.

Their appearance on 'Running Man' will begin in earnest next week. Check out the full episode below!
