Singer John Park was fooled by the hidden camera of MBC entertainment program "Infinite Challenge."

In "Infinite Challenge" aired today, the original members along with many other guests held a summer entertaiment camp special.

In the opening of the episode, MBC gagwoman Maeng Seung Ji dressed up as a reporter and held a hidden camera for John Park.

Maeng Seung Ji said to John Park, "You're the top issue online right now. Why did you do that with Lee Juk yesterday? He already told us why."

When she kept pressuring him, John Park said, "Yes, I'm sorry. I don't know what happened but if he said something, it must be right. Because I follow Lee Juk," trying to hold in his tears.
