Kim Gura made some sarcastic comments towards Co-Ed's title song, "Bbiribbom Bberibbom" on the December 1st episode of MBC's "Radio Star." Moon Hee Jun introduced the group by stating, "They have two title tracks from their digital single along with a mini-album release. They have been actively promoting thus far but aren't well known." Upon hearing one of their title tracks to be "Bbiribbom Bberibbom," MC Kim Gura sarcastically commented, "What is that? Some kind of alien speech (bbang sang)?," causing Star Light Chanmi and One Light Hyo Young to be taken aback. The 'bbang sang' was an internet phenomenon stemming from a woman that claimed to be able to converse with aliens. She made up a series of incomprehensible words such as 'bbang sang,' 'kke rang kka rang' and even had a song made up of the sounds 'bbang bbang ddong ddong ddong....' Kim Gura, who once made a broadcast appearance with the woman, went on to state, "I saw that lady in person. However, she didn't arrive on a spacecraft, she came riding the KTX." He then turned to One Light Hyo Young and asked her to pick out her part in the song. Hyo Young replied, "I sing the 'da da da da da da' part." When asked to elaborate more specifically, she replied, "I sing the 'da da da da da' part after the 'dot dot dot dot dot' part," causing the studio to burst out in laughter. Source: TV Report via Nate
