[Spoiler] Lee Seung Gi gets frustrated on 'Running Man'

Lee Seung Gi showed signs of his famous 'heodang' personality on the latest episode of 'Running Man'.

Taking on the mantle of 007, Lee Seung Gi was given a special mission to seek out the hidden spy from their midst. As the final nametag-ripping battle wound down, he found himself one of the final three to survive.

The remaining survivors, Park Shin Hye and Song Ji Hyo, soon double-teamed against Lee Seung Gi, who under duress confessed that he was, in fact, 007. A surprised Park Shin Hye then revealed that they had been given a hint, which had said 007 would know about a vital clue to solving the final puzzle.

This came as a surprise to Lee Seung Gi. Even though he had been in possession of a vital hint all along, he knew nothing of this fact, causing him to proclaim, "Am I being used by the producers?"
