Seohyun and Lee Joon appeared as guests, and when she introduced herself, Heechul didn't bother to welcome her. The Super Junior member commented, "What's the point of welcoming her," and she responded, "You be quiet," following the show's theme of a high school class.

Heechul then revealed, "Seohyun and Irene are double walls, the most boring ones at SM Entertainment. They're the same age, and they have the same name too."

What do you think of what Heechul said?
