Anyone know of Kpop choreography fails?

I know this is kinda messed up 😆 but can anyone point me towards videos where a group or artist visibly messed up the choreography or had egregiously bad dancing?

I am in awe of how in sync and perfect all the performances are that I've watched. Like how do they never accidentally run into each other or completely botch their dancing?

Like all it would take is a few inches to the left or right and there'd be potential pandemonium and they could throw off the entire dance performance.

IT NEVER FRIGGIN HAPPENS THOUGH. These idols are dance machines and it's awesome 😎

I'm not talking about "lazy" dancing necessarily but if you have any good videos of that send it my way lol. I need to know that they're human and mess up occasionally.
