Veteran actor Choi Min Soo, who terrorized the cast of SBS's 'Running Man' a few months ago at a theme park during the "Running Man Hunting" episode, is set to return on November 20th. Choi Min Soo's return promises more thrills and chills than ever, this time in a more closed�environment. In the recently released preview, Choi Min Soo's scary voice can be heard from a telephone held by a tight-faced Yoo Jae Suk. The 'nation's MC' bore the brunt of his ire in his previous outing, where he promised to return to extract his revenge against the MC for his elimination. The "grasshopper hunting" episode will be broadcast this upcoming Sunday. Source: Star News
