When asked the question "were the members ever jealous of one another?" Ok Joo Hyun answered "When I met Lee Hyori for the first time, she was wearing a baseball jersey that looked very hip hop and even though it was a loose fitting shirt, it couldn't conceal her curvy figure."

On the other hand, Shin Dong Yeop, Lee Hyori, Tak Jae Hoon, and Youjin who have MCed for 'Happy Together' in the past also made their appearances on the show.
