During Super Junior's SUPERSHOW6 concert in Beijing, Heechul got distracted and forgot to get onto the platform with his fellow members. While everyone else was rotating on a raised circular stage, Heechul continued to sing their song "Evanesce" at the base by himself. Despite the mistake, he took it all in stride and in a very professional manner. However, some other Super Junior members couldn't quite hide their surprise!

You can fast forward to 0:45 seconds in to see the start of Heechul's confusion!

See Shin Ha Kyun as an elderly chaebol who ages in reverse in the romantic comedy Mr. Baek:

Pretty hilarious, right? I just love when Siwon covers his mouth to hide his laughter and then slyly moves to fill in the large gap in the circle. Smooth move!
