BTOB always knows how to liven(?) up a performance!

On September 12 KST, the Cube Entertainment boy group performed their final music show stage of current promotional single "Outsider" on SBS's 'Inkigayo,' where they turned heads and made fans laugh with a zombie concept performance. For the stage, the members reprised the 'Warm Bodies' theme from the song's music video, coming on stage in playfully spooky zombie costumes.

In particular, during the normal 'ending fairy' portion of the performance, member Changsub stared blankly into the camera before the other three members moved into the frame to attack him.

Screencaps of the scene went viral on various Korean online communities, with one netizen naming their post, "BTOB, who said today's 'Inkigayo' was their final broadcast and wore Halloween grade high-quality zombie costumes. The zombie ending is freaking hilarious."

Netizens who responded to the post found the ending both charming and hilarious, leaving comments like, "This is the first time I've felt that I want to marry a zombie," "No way, why are they like this, haha," and "Lee Changsub looks like he might be sick lol."

Other netizens who seemed to be fans of the group also informed that this was just BTOB 'as usual,' saying, "BTOB 'BTOB'ed" and "BTOB ended their broadcasts in a BTOB way."

Meanwhile, BTOB released their special album '4U: OUTSIDE' on August 30.
