So, Onew from SHINee has this thing called "Onew Condition", or directly in Korean, "Onew Sangtae". He's pretty famous for it. It's pretty much were he makes mistakes.

Such as walking off stage in the opposite direction ([link]), choking on water ([link]), tripping, doing wrong dance moves, making random noises on radio shows, doing weird expressions when he doesn't know the camera is on him, setting things on fire, falling down the stairs (which got SHINee's comeback delayed for two weeks because he dislocated his front two teeth), telling lame jokes, or in all, anything he does that makes the atmosphere really silent. Or everyone bursts out laughing. But not how it was intended to be.

Here's the video, in case anyone wants to see how fail it was.

Just go to about 1:20, that's when he's walking towards it.
He's in the the tye-dye shirt with the yellow skinny jeans.
