On this week's episode of MBC's 'Weekly Idols',�SISTAR made an appearance as guests and participated in an unusual competition. During a segment of the show called 'Beat the Idols', SISTAR competed against MCs Jung Hyung Dong and Defconn in a gum spitting competition called, 'Gum Archery'. Soyu, Dasom, Bora, and Hyorin seemed hesitant at first, saying, "How can we spit gum at the target when we're female idols?" However, once they were handed the gum, they started to chew vigorously and gave it their all during the competition. Their easy-going nature and fierce competitiveness brought laughter to the viewers. Despite their best efforts, however, all the members were defeated by Jung Hyung Dong. The losers had to face a severe penalty of eating spicy foods, but the PD decided to give them the option to leave early, bringing about complaints from Jung Hyung Dong. Meanwhile, Defconn took this time to pick up the gum that SISTAR had spat out, stating, "I'm going to sell this", which caused the�viewers to roar with laughter.
