B2ST were guests on the July 14 airing of 'Park Myung Soo's Radio Show,' during which they entertained the listeners with their witty back and forth with the DJ. 

DJ Park Myung Soo didn't refrain from pushing the members' buttons, bringing up the past failed shows that they were on together.

The DJ said, "'100 Points out of 100' failed because Yoseob didn't do well. 'Hot Brothers' also failed thanks to Kikwang. I worked so hard on those programs." Yoseob and Kikwang, clearly flustered at this sneak attack from Park Myung Soo, were left speechless and dazed. It's okay boys, Park Myung Soo was just joking!
