Singer Psy revealed that Yoon Do Hyun had played a part in Psy's popularity and signing with Justin Bieber's label.

The September 26th episode of SBS's "One Night of TV Entertainment" covered Psy's return to Korea after his popularity explosion in America. During a segment, Psy revealed, "Actually, the reason I could sign with an American label is because of Yoon Do Hyun. I don't know how much alcohol I should buy him for repayment."

At this, Yoon Do Hyun replied, "I am friends with a producer in the label that Psy signed a contract with. I was on my skateboard and the friend asked me to connect him to Psy. I treated the situation as if I was in that same position and connected the two of them."

At this, co-host Sooyoung jokingly said, "You know my number right? I'm available anytime."
