Lee Kwang Soo turned into a trickster on the latest episode of 'Running Man'.

The latest episode found the cast members and the guests - 4minute's HyunA, Park Sung Woong, and Hwang Jung Min - divided up into two teams. The goal was the collect all seven of the suitcases that were hidden in the final location.

Near the end of the episode, only Lee Kwang Soo remained on one side while Kim Jong Kook and Ji Suk Jin remained on the opposing team. Since only the 'giraffe' knew the locations for his team's suitcase collection, it was unwise to rip his nametag, as the locations would disappear along with him.

Lee Kwang Soo taunted the other side by showing off one of his suitcases, letting each of them hold it for a few seconds. It was at that moment that Lee Kwang Soo chose to strike, quickly ripping off Kim Jong Kook's nametag when both of his hands were occupied with the suitcase.

Supported by his wily brains, Lee Kwang Soo emerged as the hero for his team, drawing the applause of everyone on his side.
