SEE ALSO: B2ST's Yoseob and Jun Hyun Moo are joining 'I Live Alone'

On the October 25th broadcast of MBC's 'I Live Alone', Yoseob and Noh Hong Chul went shopping for house supplies for Yoseob's bachelor pad when the comedian spotted a fly sticker that can be attached to men's urinals to encourage men to aim better and prevent splashing when taking their bathroom breaks. 

With his 4D way of thinking, Noh Hong Chul decided this would be a great present for Yoseob to help keep his new place clean, and bought the sticker. Once back at Yoseob's, Noh Hong Chul tried several failed attempts to get the sticker to stay in place, while Yoseob said multiple times, "It's weird. I don't need it."

However, the comedian kept his pursuit and finally thought that he managed to get the sticker to stay in place. He then decided to test out its efficiency for himself, but unfortunately the sticker ended up flushing down the toilet. 

Yoseob hilariously shared his honest feelings during his one-on-one interview, "Noh Hong Chul gets quite obsessed. The fly sticker is something that I really don't need. I was surprised at how persistent he was about the fly."

When asked why he was so persistent about the sticker, Noh Hong Chul said during his interview portion, "I just wanted to buy him something, but it seemed like he had everything he needed, so I thought this would be good," as well as, "I think the sticker was definitely not made for household toilets. It only works on those long, public men's urinals. But because I'm the hyung, I wanted to show him the importance of working hard until the very end... But I didn't know what to do when the sticker fell to my surprise."
