On the November 2 airing of 'Weekly Idol,' the show did not have a new guest but showed never-before-seen clips of previous guests!

This included a clip of Red Velvet from when they were promoting "Russian Roulette." The girls tried their hand at dancing to the song at twice the speed! �This didn't make it to the official broadcast, but was saved as a treat for today's special show.

The girls' song is super fast, but they work hard and work well. �There's one collision, but in the end, does the group succeed? �See for yourself above!
